Abstract

Esters of acrylic and/or methacrylic acid, such as ethyl acrylate and methyl and butyl methacrylates, with, if desired, one or more other polymerizable monomers, are bulk polymerized under the influence of one or more catalysts and in the presence of one or more organic compounds containing -SH groups, such as thioglycollic acid, methyl thioglycollate, mercaptoethanol and aliphatic mercaptans, the esters, together with, if desired, other polymerizable monomers being run into a mixture of the same or similar composition which is being polymerized at a temperature above that of the esters or other monomers, the rate of addition of monomeric material preferably not exceeding the rate of polymerization. Catalysts specified are benzoyl peroxide, lauroyl peroxide, cyclohexanone peroxide, mixed aliphatic-aromatic peroxides, and azodi-isobutyric acid dinitrile. Phthalic anhydride may be added to the reaction mixture to reduce the melting point of the product. The polymers produced may be incorporated in alkyd resins in an appropriate stage in their preparation, for example (1) polymethyl methacrylate in admixture with phthalic anhydride is boiled with a mixture of the monoglycerides of linseed, soya and castor oils, followed by the addition of more phthalic anhydride and further heating; (2) a copolymer of methyl and butyl methacrylates is heated with glycerin, pentaerythritol, and phthalic and maleic anhydrides followed by the addition of the monoglycerides of linseed and castor oils and further heating; and (3) polyethyl acrylate is heated with a mixture of linseed oil mono- and di-glycerides and a precondensed alkyd resin made from trimethylol propane and phthalic anhydride.
