Title:

NOVEL RESIN-LINEAR ORGANOPOLYSILOXANE BLOCK COPOLYMER, USE OF SAME, AND METHOD FOR PRODUCING SAME

Document Type and Number:

WIPO Patent Application WO/2018/066572

Kind Code:

A1

Abstract:

Provided is a novel resin-linear organopolysiloxane block copolymer which has a high degree of freedom in formulation due to excellent compatibility with other lipophilic starting materials, and which exhibits excellent film forming properties and followability of a film, while being suppressed in stickiness of a film or the like. This resin-linear organopolysiloxane block copolymer has a resin structure (A1) block that has siloxane units represented by R1SiO3/2 (wherein R1 represents a monovalent organic group, a hydroxyl group or an alkoxy group having 1-6 carbon atoms) and SiO4/2, and a linear structure (A2) block represented by (R2SiO2/2)n (wherein n represents a number of 5 or more; and R represents an alkyl group, a fluoroalkyl group or an aryl group) in each molecule; the resin structure (A1) and the linear structure (A2) are linked to each other by an Si-O-Si bond; and an Si atom bonded to the resin structure (A1) constitutes an RSiO3/2 unit.
