LOW TEMPERATURE IMPACT MODIFIERS WITH GOOD TRANSPARENCY AND WEATHERABILITY
Document Type and Number:
WIPO Patent Application WO/2020/244485
Kind Code:
A1
Abstract:
Disclosed are a graft copolymer with core-shell structure, a process for the preparation of the graft copolymers, a process for producing a thermoplastic resin, and a mixture of the graft copolymer with core-shell structure. The core is produced by several steps of a successive emulsion polymerization of one or more monomers in the presence of one or more plasticizers, the plasticizer content being 10 to 80%and the monomer content being 90 to 10%. The graft copolymer with core-shell structure ensures impact modifiers for low temperature applications with good transparency and weatherability.
