Title:
ADDITIVE FOR RESIN KNEADING
Document Type and Number:
WIPO Patent Application WO/2022/054893
Kind Code:
A1
Abstract:
This additive for resin kneading comprises an organic UV absorber and/or a radical scavenger and a polymer in which the organic UV absorber and/or the radical scavenger are dispersed. The additive for resin kneading is in the form of powder particles. The additive for resin kneading has a median size of 1-100 μm inclusive. In the additive for resin kneading, the percentage of the total amount of the organic UV absorber and the radical scavenger is 20-70 mass% inclusive. The polymer is a copolymer of vinyl monomer components that comprise a monofunctional vinyl monomer containing only one polymerizable carbon-carbon double bond per molecule and a polyfunctional vinyl monomer containing two or more polymerizable carbon-carbon double bonds per molecule. Relative to the total amount of the monofunctional vinyl monomer and the polyfunctional vinyl monomer, the percentage of the monofunctional vinyl monomer is 10-95 mass% inclusive.
