Title:

POWDER OF POLYORGANOSILOXANE-CONTAINING GRAFT COPOLYMER, RESIN COMPOSITION INCLUDING SAME, AND MOLDED OBJECT OF SAID RESIN COMPOSITION

Document Type and Number:

WIPO Patent Application WO/2019/168007

Kind Code:

A1

Abstract:

The purpose of the present invention is to provide a powder of a polyorganosiloxane-containing graft copolymer capable of giving both an aromatic polyester resin composition having an excellent balance between colorability and impact resistance and a molded object. The powder of a polyorganosiloxane-containing graft copolymer according to the present invention is a powder of a polyorganosiloxane-containing graft copolymer obtained by graft-polymerizing a mixture (B) of an epoxidized vinyl monomer (b1) and other vinyl monomer(s) (b2) with a rubber (A) including a polyorganosiloxane, wherein the content of the polyorganosiloxane (A1) in the rubber (A) is 12-50 mass% and the polyorganosiloxane-containing graft copolymer has a weight-average particle diameter of 300-2,000 nm and an epoxy equivalent of 2,500-7,800 g/eq.
