Abstract:
The present invention relates to a silicone-acrylic impact modifier having multi-layer structure and a thermoplastic resin composition containing the same, more precisely a silicone-acrylic impact modifier which is composed of i) silicone rubber seed containing one or more vinyl copolymers; ii) acrylic rubber core covering the seed; and iii) a shell containing one or more vinyl copolymers covering the acrylic rubber core, and a thermoplastic resin composition containing the same. The thermoplastic resin having the silicone-acrylic impact modifier of the present invention has improved impact resistance and colorability.
