Abstract
PURPOSE:To obtain a thermoplastic resin excellent in heat stability and high-temperature dimensional stability, by partially polymerizing a monomer mixture containing acrylonitrile and alpha-methylstyrene and, after addition of methyl methacylate and supplemental amount of the vinyl monomers, bringing the polymerization to completion. CONSTITUTION:In the production of a thermoplastic terpolymer resin by polymerizing a monomer mixture consisting of alpha-methylstyrene, methyl methacrylate and acrylonitrile; in the first stage, a mixture of 75-85wt% alpha-methylstyrene and 25-15wt% acrylonitrile is polymerized until the amount of polymer formed reaches 50wt% or more of the weight of the final copolymer. Next, in the second stage, the polymerization is brought to completion by the addition of the vinyl monomers is amounts which provide a vinyl monomer mixture of alpha-methylstyrene, methyl methacrylate and acrylonitrile, of a composition falling in the range defined by the coordinate points A, B, C and E shown, while taking the amounts of the monomers remaining after the first stage polymerization into account.
