Abstract: A thermoplastic terpolymer resin composition of improved resistance to ultraviolet light deterioration consisting essentially of a rubbery copolymer backbone of a C2 to C18 alkyl acrylate and a first member of ethylthioethyl methacrylate having grafted thereon a graft copolymer of acrylonitrile and styrene member, said terpolymer composed of between about 15 and 35 weight percent of said rubbery backbone and between 65 and 85 weight percent of said graft copolymer, said rubbery backbone component having a first weight ratio of said alkyl acrylate to said first member of between about 99:1 and 99:10 and said graft copolymer component having a weight ratio of said acrylonitrile to said styrene member of between about 15:85 and 30:70, said styrene member selected from the group consisting of styrene and between about 1:0 and 1:1 weight mixture of styrene to Alpha methylstyrene, said terpolymer composition formed by the method consisting essentially of first polymerizing a mixture of said alkyl acrylate and said member under aqueous emulsion polymerization conditions in the presence of polymerization initiator, polymerization modifier and first anionic emulsifier to form an aqueous latex containing a copolymer of acrylate and said member, said first polymerization being conducted at a pH between about 2 and 7 at a first temperature between about 110* and 150* F. under conditions of vigorous agitation thereby forming the rubbery copolymer of alkyl acrylate and first member, then second polymerizing under aqueous emulsion conditions said formed alkyl acrylate-first member copolymer with a mixture of acrylonitrile and styrene member in the presence of polymerization initiator, polymerization modifier and a second anionic emulsifier, said second polymerization being conducted at a pH of between 2 and 7 at a second temperature between about 110* and 150* F. under vigorous agitation conditions until said terpolymer composition is formed.
