Title:
TRANSPARENT RUBBER-MODIFIED STYRENE-BASED RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2022/224926
Kind Code:
A1
Abstract:
Provided is a rubber-modified styrene-based resin composition having excellent transparency and surface impact strength. The present invention provides a rubber-modified styrene-based resin composition containing: a continuous phase including a styrene-based copolymer; and dispersed particles including a rubbery polymer, wherein the styrene-based copolymer contains a styrene-based monomer unit and at least one (meth)acrylic acid ester-based monomer unit, the rubber-modified styrene-based resin composition has a graft ratio of 2.12-2.40, and the rubbery polymer has a hydrogenation ratio of less than 7 mol%.
