<p>Impact resistant thermoplastic composition comprises (A) 5-50 pats by weight of a graft copolymer and (B) 95-50 parts by weight of an aromatic vinyl polymer having syndiotactic structures, wherein (A) is obtained by adding (b) 0.1- 15 parts by weight of a copolymer latex containing acid groups and being prepared by polymerising a monomer mixture consistinf of 5-25 wt.% of a unstaturated carboxylic acid and 95-75 wt.% of a comonomer, into (a) 100 parts by weight (solid contents) of latex rubber particles having an average particle diameter of 300 A or less to obtain (c) enlarged rubber particles through coagulation and having an average particle diameter of 3000-20000 A, and then polymerising 40-15 wt.% of (c) with 60-15 wt.% of (d) a monomer mixture containing 20-100 parts by weight of an aromatic vinyl monomer. An independent claim is also included for a resin composition comprising 100 parts by weight of the above composition, and 0.01-100 parts by weight of an additive selected from inorganic fillers, crystalline nucleating agent, anti-oxidation agent, flame retardant, anti-charge agent, lubricants and pigments.</p> |
