Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to candles based on 4-methyl-1-pentene polymers.

Many candle bases have been proposed in the past, but very few of them are transparent, and they have not yet been widely commercialized.

The main reason for this is thought to be that a candle base that is not only transparent but also bright, burns without producing smoke or soot, and does not produce harmful substances or odors has not been found. Ru. Further, as a candle base, it is preferable to use one that causes blocking during storage or softens during use so that it does not mirror the candle. Moreover, it is desirable that it be easy to mold, have hardness above a certain level, and not easily break. As a result of examining candle bases having such various properties, the present inventors have discovered that a specific 4-methyl-1-pentene polymer has both of these properties.

That is, in the present invention, the average molecular weight is 300 to 5,000.
O-SOKU is based on 4-methyl-1-bentene polymer. The 4-methyl-1-bentene polymer used in the present invention is a homopolymer of 4-methyl-1-bentene or 4-methyl-1-bentene and other a-olefins, such as 1-butene, 3-methyl-1-phthene, 1-bente, 1 It is a copolymer with -hexene, 3-methyl-1-pentene, 1-ocdene, 1-decene, 1-tetradecene, 1-octadecene, or a mixture thereof. A preferred copolymer of 4-methyl-1-pentene is 4-methyl-1-pentene.
-Methyl-1-pentene content is 50 mol% or more, particularly 70 mol% or more.

Of course, the copolymer may be a mixture of two or more copolymers having different contents of 4-methyl-1-pentene, and in that case, the content of 4-methyl-1-pentene in the mixture is within the above range. It is preferable that the The average molecular weight (Mm) of the 4-methyl-1-pentene polymer is 300 and 5.
,000 range.

The average molecular weight (Mn) here is determined in triclene at 70° C. according to the vapor pressure osmotic pressure method. The 4-methyl-1-pentene polymer having the above properties can be produced by using, for example, a transition metal compound component, such as a titanium catalyst component, and an organometallic compound catalyst component, such as an alkyl aluminum compound, as the main catalyst components, to form a high molecular weight 4-methyl-1-bentene polymer. It can be obtained as a creation material when manufacturing polymers. For example, it can be isolated as a hydrocarbon-based component during the above polymerization, and if necessary, it can be extracted with a mixed solvent of hydrocarbon and oxygen-containing solvent, such as alcohol or ketone, to isolate a substance with a predetermined average molecular weight. Can be done. Alternatively, it can also be directly produced by allowing a large amount of hydrogen to coexist during the polymerization. Furthermore, it can also be produced by thermally decomposing a high molecular weight 4-methyl-1-pentene polymer with or without addition of an organic peroxide, or by further hydrogenating it if necessary. In manufacturing candles, it is possible to use only 4-methyl-1-bentene polymer.

However, various additives can be mixed and used for strength improvement, coloring, and other purposes. For example, oils such as paraffin oil and naphthenic oil, higher fatty acids, higher alcohols, higher fatty acid esters, paraffin wax, polyethylene wax, natural waxes, antioxidants, anti-aging agents, ultraviolet fabric absorbers, pigments, dyes, and coloring agents. , a thermochromic coloring agent, a port dissolving agent, etc. can be blended.
According to the present invention, it is possible to provide a candle that is transparent, has excellent decorative functions, and does not generate soot or odor when burned, so that it can be used in various places such as homes, restaurants, and churches.

Examples and Comparative Examples A sample was placed in a cylindrical gold crusher, a candle was made using a compression molding machine, and a combustion test was conducted.
