Abstract

PURPOSE: To obtain a copolymer having improved color tone, impact and heat resistance, by adding a vinyl cyanide monomer at a specific rate to an emulsion polymerization system of an aromatic vinyl monomer and another vinyl monomer from the initial stage to polymerize the monomers.
CONSTITUTION: (A) An aromatic vinyl monomer, e.g. α-methylstyrene, and (B) a vinyl monomer, e.g. acenaphthylene, are dissolved in water to give an aqueous solution thereof containing 65W80wt% the component (A) and 0W20wt% the component (B) based on the monomers. A water-soluble free radical generator, e.g. potassium persulfate, and an emulsifier, e.g. sodium dodecylbenzenesulfonate, are added thereto to carry out the aqueous emulsion polymerization. (C) 15W30wt% cyanide monomer, e.g. acrylonitrile, is added at a lower rate than the polymerization rate to the emulsion polymerization system from the initial polymerization stage to carry out the polymerization while keeping the total number of moles of the components (A) and (B) at 1.5W3 times that of the component (C) during the rate of polymerization in the range of 0W90% to give the aimed copolymer.
