Rubber-reinforced vinyl polymer latex, rubber-reinforced vinyl-based polymer and thermoplastic polymer composition for base rubber for rubber-reinforced vinyl polymer

摘要

The present invention relates to a rubber-reinforced vinyl-based resin composition which is excellent in moldability, mold non-staining property such as impact resistance, surface luster, thermal stability, color tone, etc. and has few foreign matters (heat discoloration) A rubber-like vinyl polymer for base rubber used as a raw material for producing a polymer, a rubber-reinforced vinyl polymer obtained by using such a rubber-like polymer, and a composition thereof.;According to the present invention, 100 parts by weight of a monomer component capable of forming rubber (a) is mixed with 100 parts by weight of (b) a reactive emulsifier (n-1) / another emulsifier A rubber-reinforced vinyl polymer obtained by emulsion-polymerization in the presence of 0.01 to 10 parts by weight of an emulsifier, a rubber-reinforced vinyl polymer obtained by polymerizing a vinyl monomer in the presence of the rubber-like polymer latex for base rubber, There is provided a thermoplastic polymer composition obtained by blending a reinforced vinyl polymer with a thermoplastic polymer.
