Abstract

1460139 Acrylic elastomers STAUFFER CHEMICAL CO 8 May 1975 [1 July 1974] 19394/75 Heading C3P A method of making acrylic elastomer containing interpolymer particles by the emulsion polymerization of a monomer charge containing at least one monomer capable of forming a cross-linked acrylic rubber having a glass transition temperature of less than 25‹ C. and a monomer having at least two ethylenically unsaturated bonds as a cross-linking agent to form an aqueous emulsion which contains cross-linked acrylic elastomer particles and by thereafter suspension polymerizing a monomer charge comprising vinyl chloride in the presence of the acrylic elastomer particles is characterized in that a sulphonated salt of an ethoxylated alkyl phenol is used as the emulsifier in the emulsion polymerization step. Numerous examples of the monomer that form acrylic elastomers, and of optimal monomers which together with the vinyl chloride are thereafter polymerized in the presence of the acrylic elastomer are specified. The preferred crosslinking agent is butylene glycol diacrylate. A coagulant may be added to the suspension batch either prior to, during, or after the suspension polymerization is run in order to facilitate complete precipitation of the elastomer latex particles. Suitable coagulants are calcium chloride, ferric chloride, barium chloride, magnesium chloride, aluminium chloride, aluminium chloride hexahydrate, aluminium sulphate, calcium sulphate and polyvinylpyridinium butyl chloride. Suspending agents such as methyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, carboxymethyl cellulose, talc, clay, polyvinyl alcohol and gelatin are present in the aqueous emulsion of the rubber polymer particles. Polymerization may then be initiated by reacting the vinyl chloride in the presence of the acrylic elastomer particles at 45-75‹ C. for 2-12 hours. Preferred products contain 30-55% by weight of the cross-linked acrylic elastomer emulsion polymer and 45-70% by weight of the vinyl chloride suspension polymer surrounding and/or homogeneously dispersed throughout the mass of the said elastomer emulsion polymer. In the specific Example (1) a blend of n-butyl acrylate, 2-ethylhexyl acrylate and butylene glycol diacrylate is emulsion polymerized in the presence of the sodium salt of an alkyl aryl polyether sulphonate emulsifier to form an aqueous emulsion containing cross-linked acrylic elastomer particles to which is added vinyl chloride and calcium chloride, as coagulant. The comparative example uses the same monomers and conditions except that sodium lauryl sulphate is used in the emulsion polymerization step. Reference has been directed by the Comptroller to Specification 1,362,277.
