Title:
ACRYLATE-BASED COPOLYMER, METHOD FOR PRODUCING SAID COPOLYMER, FRICTION INHIBITOR USING SAID COPOLYMER, AND LUBRICATING COMPOSITION CONTAINING SAID FRICTION INHIBITOR
Document Type and Number:
WIPO Patent Application WO/2020/246445
Kind Code:
A1
Abstract:
The present invention provides an acrylate-based copolymer obtained by polymerizing constituent monomers including, with respect to the total number of moles of the constituent monomers, 10-95 mol% of a polymerizable monomer (a) composed of an alkyl acrylate-based monomer represented by general formula (1), 5-50 mol% of a polymerizable monomer (b) composed of an alkylene glycol acrylate-based monomer represented by general formula (2), and 0-60 mol% of at least one polymerizable monomer (c) selected from the group consisting of an aromatic vinyl-based monomer (c-1) and a short-chain alkyl acrylate-based monomer (c-2) represented by general formula (3). (In formula (1), R1 represents a C4-18 alkyl group, and A1 represents a hydrogen atom.) (In formula (2), R2 represents a C2-4 alkylene group, R3 represents a hydrogen atom or a C1-30 alkyl group, A2 represents a hydrogen atom, and n represents a number of 2-20.) (In formula (3), R4 represents a C1-3 alkyl group, and A3 represents a hydrogen atom.)
