ABSTRACT OF THE DISCLOSURE A thermoplastic resin having excellent impact resistance and heat resistance obtainable by poly- merizing 93 to 30 parts by weight of a monomer mixture comprising 20 to 90% by weight of at least one .alpha.-alkyl- aromatic vinyl monomer, 10 to 40% by weight of at least one vinyl cyanide monomer and 0 to 60% by weight of at least one vinyl monomer copolymerizable therewith (100% by weight in total) in the presence of 7 to 70 parts by weight (in terms of solid) of a rubber latex of a large particle size having a particle diameter of at least 0.2 µm obtained by adding 0.1 to 5 parts by weight (in terms of solid) of an acid-group containing copolymer (B) latex obtained from 3 to 30% by weight of an acid-group containing monomer, 97 to 35% by weight of at least one alkyl acrylate having 1 to 12 carbon atoms in the alkyl group, and 0 to 48% by weight of at least one vinyl monomer copolymerizable therewith (100% by weight in total) to 100 parts by weight (in terms of solid) of a rubber (A) latex of a small particle size having a pH of 7 or higher obtained from 100 to 50% by weight of 1,3-butadiene and 0 to 50% by weight of a monomer having CH2 = Image group and copolymerizable therewith (100% by weight in total).
