Description

シリコーンモノマー及びその製造方法Silicone monomer and method for producing the same
 本発明は、コンタクトレンズ、眼内レンズ、人工角膜等の眼科デバイスを製造する際に利用可能な、重合性を有するシリコーンモノマー、その製造方法、該シリコーンモノマーを用いた単量体組成物及び重合体に関する。 The present invention relates to a polymerizable silicone monomer that can be used in the production of ophthalmic devices such as contact lenses, intraocular lenses, and artificial corneas, a method for producing the same, a monomer composition using the silicone monomer, and a weight thereof. Regarding coalescence.
 生体用デバイスを含む種々の物品は、例えば、有機ケイ素化合物含有材料から形成されている。ソフトコンタクトレンズなどの生体用デバイスに有用な有機ケイ素化合物材料の一つにケイ素含有ヒドロゲル材料が挙げられる。一般に、ケイ素系の材料は、水よりも高い酸素透過性を有するので、より高い酸素透過性を有する物品が提供できる。
 従来ハードコンタクトレンズに用いられている有機ケイ素化合物材料は、高酸素透過性であるが、ソフトコンタクトレンズに用いられる材料よりも硬い。また、このような有機ケイ素化合物材料は疎水性であるため、これを用いてレンズを製造するには、親水性表面を提供するための追加の処理を必要とする。
 眼科デバイスに用いられる眼用のシリコーンモノマーとして、例えば、下記TRIS(3-[トリス(トリメチルシロキシ)シリル]プロピルメタクリレート)が知られている(特許文献1)。
Various articles including a biological device are formed from, for example, an organic silicon compound-containing material. One organosilicon compound material useful for biomedical devices such as soft contact lenses is a silicon-containing hydrogel material. In general, silicon-based materials have higher oxygen permeability than water, and therefore, articles having higher oxygen permeability can be provided.
Organosilicon compound materials conventionally used for hard contact lenses are highly oxygen permeable, but are harder than materials used for soft contact lenses. Also, since such organosilicon compound materials are hydrophobic, manufacturing lenses using them requires additional processing to provide a hydrophilic surface.
As an ophthalmic silicone monomer used for an ophthalmic device, for example, the following TRIS (3- [tris (trimethylsiloxy) silyl] propyl methacrylate) is known (Patent Document 1).
Figure JPOXMLDOC01-appb-C000004
Figure JPOXMLDOC01-appb-C000004
 TRISも疎水性のモノマーであるため、眼用レンズ素材として用いる場合には、例えば、親水性モノマーと共重合させることが考えられる。しかし、TRISは、HEMA(2-ヒドロキシエチルメタクリレート)のような親水性モノマーとの相溶性に劣り、このような親水性モノマーと共重合させた場合、透明ポリマーが得られず、レンズ素材として使用できない。また、N-ビニルピロリドンやN,N-ジメチルアクリルアミドなど、他の親水性モノマーとの組み合わせの多くは含水時に表面が強く撥水するために、TRISはソフトコンタクトレンズ用素材として使用しにくいことが知られている。
 これを改善する目的で、特許文献2及び3には、SiGMA(メチルジ(トリメチルシロキシ)シリルプロピルグリセロールメタクリレート)が提案され、シリコーンハイドロゲルコンタクトレンズ用途において相溶化剤モノマーとして使用されている。SiGMAは、適度な酸素透過性能を有するために酸素透過製剤としての役割も果たしている。該SiGMAは水酸基を有していることから良好な親水性を発現することが知られている。
Figure JPOXMLDOC01-appb-C000005
Since TRIS is also a hydrophobic monomer, when used as an ophthalmic lens material, for example, it may be copolymerized with a hydrophilic monomer. However, TRIS has poor compatibility with hydrophilic monomers such as HEMA (2-hydroxyethyl methacrylate). When copolymerized with such hydrophilic monomers, transparent polymers cannot be obtained and used as lens materials. Can not. In addition, many combinations with other hydrophilic monomers such as N-vinylpyrrolidone and N, N-dimethylacrylamide have a strong water repellency when containing water, so TRIS is difficult to use as a material for soft contact lenses. Are known.
In order to improve this, Patent Documents 2 and 3 propose SiGMA (methyldi (trimethylsiloxy) silylpropylglycerol methacrylate), which is used as a compatibilizer monomer in silicone hydrogel contact lens applications. Since SiGMA has an appropriate oxygen permeation performance, it also plays a role as an oxygen permeation preparation. Since this SiGMA has a hydroxyl group, it is known to express good hydrophilicity.
Figure JPOXMLDOC01-appb-C000005
 レンズの装用感に悪影響を与えるオリゴマー架橋成分を低減する方法として、特許文献4にSiGMAの新たな製造方法も提案されている。しかしながら、モノマー1分子内のシロキサニル基が占める質量割合をシリコーン含量と定義したとき、SiGMAはシリコーン含量が52.4%(SiGMAの1分子中のシロキサニル基を構成する各原子の原子量の合計は221であり、SiGMAの分子量が422であるから、このときのシリコーン含量は、221/422×100=52.4%と計算できる。)であり、TRISのシリコーン含量72%と比較して、ケイ素含量が低いため、十分な酸素透過性を得ることが困難であった。 As a method for reducing oligomer crosslinking components that adversely affect the wearing feeling of the lens, Patent Document 4 proposes a new method for producing SiGMA. However, when the mass ratio of the siloxanyl group in one monomer molecule is defined as the silicone content, the SiGMA has a silicone content of 52.4% (the total atomic weight of each atom constituting the siloxanyl group in one molecule of SiGMA is 221). Since the molecular weight of SiGMA is 422, the silicone content at this time can be calculated as 221/422 × 100 = 52.4%.) Compared with the silicone content of TRIS of 72%, the silicon content Therefore, it was difficult to obtain sufficient oxygen permeability.
 特許文献5には分子内にアミド結合を有する下記式で示されるシリコーンモノマーTMSAAが提案されている。該シリコーンモノマーは、アミド基を有することからTRISと比較して親水性が向上している。
 しかし、十分な親水性を得るには至っておらず、これを用いてソフトコンタクトレンズを調製した際にはレンズ表面が疎水性になり、表面の親水化処理等を行なう必要がある。そのため、製造工程が複雑になるという問題があった。
Figure JPOXMLDOC01-appb-C000006
Patent Document 5 proposes a silicone monomer TMSAA represented by the following formula having an amide bond in the molecule. Since the silicone monomer has an amide group, the hydrophilicity is improved as compared with TRIS.
However, sufficient hydrophilicity has not been obtained, and when a soft contact lens is prepared using this, the lens surface becomes hydrophobic, and it is necessary to perform a hydrophilic treatment on the surface. Therefore, there has been a problem that the manufacturing process becomes complicated.
Figure JPOXMLDOC01-appb-C000006
 特許文献6には、メタクリル酸ハライドとオリゴエチレングリコール変性直鎖シリコーンとの反応による新たなモノマーが提案されている。オリゴエチレングリコールは、分子内のエーテル基と共に末端の遊離水酸基が大きく親水性に寄与する。しかし、該モノマーの水酸基はエステル結合を形成しているため十分に機能せず、親水性を得るためには、エーテル構造の繰り返し単位を多くする必要がある。そのため、モノマー中のシリコーン含量は下がる傾向にあり、レンズの表面親水性と酸素透過性とを同時に満たすことは困難であった。 Patent Document 6 proposes a new monomer by reaction of methacrylic acid halide with oligoethylene glycol-modified linear silicone. Oligoethylene glycol has a large free hydroxyl group at the terminal as well as an ether group in the molecule and contributes to hydrophilicity. However, the hydroxyl group of the monomer does not function sufficiently because it forms an ester bond, and in order to obtain hydrophilicity, it is necessary to increase the number of repeating units of the ether structure. For this reason, the silicone content in the monomer tends to decrease, and it has been difficult to satisfy both the surface hydrophilicity and oxygen permeability of the lens.
 特許文献7には、3級アミンとハロゲン化アルキルとの反応により得られる、式(3)で表される分子内に4級アンモニウムを有するシリコーンモノマーが提案されている。このモノマーは、重合によりレンズ表面の親水性は達成されるが、シリコーン含量は295/587=50.3%とSiGMAと同程度であり、酸素透過性を満足することが困難である。また該モノマーはカチオン性であるため、これを用いたレンズではタンパク質吸着など、レンズ表面の白濁汚れが懸念される。
Figure JPOXMLDOC01-appb-C000007
Patent Document 7 proposes a silicone monomer having a quaternary ammonium in the molecule represented by the formula (3), which is obtained by a reaction between a tertiary amine and an alkyl halide. This monomer achieves the hydrophilicity of the lens surface by polymerization, but the silicone content is 295/587 = 50.3%, which is similar to SiGMA, and it is difficult to satisfy oxygen permeability. Further, since the monomer is cationic, there is a concern that the lens surface using the monomer may cause white turbid contamination on the lens surface such as protein adsorption.
Figure JPOXMLDOC01-appb-C000007
 以上の事情から、眼科デバイスに用いられる眼用のシリコーンモノマーの分野では、新たな分子構造の親水性を有するシリコーンモノマーであって、製造が容易で、一日使い捨てレンズのような安価な用途にも使用可能な、且つモノマー1分子内にシロキサニル基が占める割合(シリコーン含量)が大きいシリコーンモノマーの開発が求められている。 From the above circumstances, in the field of ophthalmic silicone monomers used in ophthalmic devices, it is a silicone monomer having a hydrophilicity with a new molecular structure, which is easy to manufacture and is inexpensive for daily disposable lenses. There is a need to develop a silicone monomer that can be used and has a large proportion (silicone content) of siloxanyl groups in one monomer molecule.
