POLYORGANOSILOXANE-CONTAINING GRAFT COPOLYMER, RESIN COMPOSITION USING THE SAME, AND MOLDED PRODUCT COMPRISING THE COMPOSITION

Document Type and Number:

Japanese Patent JP2019218419

Kind Code:

A

Abstract:

To provide a polyorganosiloane-containing graft copolymer which has improved impact resistance while maintaining its inherent rigidity as a thermoplastic resin, and which exhibits, in a molded product obtained from a thermoplastic resin, a high color developing property to provide a molded product having excellent appearance, and to provide a thermoplastic resin composition having such properties as mentioned above and a molded product.SOLUTION: Provided is a polyorganosiloane-containing graft copolymer obtained by graft polymerizing a vinyl monomer (b) to a rubber (A) comprising a polyorganosiloxane (A1) and a vinyl polymer (A2), where a refractive index is 1.47-1.60, a weight average particle diameter is more than 50 nm and less than 300 nm, and the rubber (A) contains an aromatic vinyl monomer unit in an amount of more than 30 mass% and 90 mass% or less.SELECTED DRAWING: None
