ABSTRACT:
A multi-layered polymer having (a) a core layer of an aromatic vinyl polymer, (b) an intermediate layer of a butadienic rubbery polymer and (c) an outer layer of an aromatic vinyl glassy polymer, the amount of the components (a), (b) and (c) being 12 to 42 weight %, 48 to 78 weight % and 10 to 40 weight %, respectively, provides a thermoplastic resin composition excellent not only in impact strength, especially in impact strength at low temperatures, but also in, in the case of containing a coloring agent, color-stability including less mottlings, and giving a molded article improved in preventing occurrence of delamination around the gate region.
