Title:
POLYMER, FRICTION MODIFIER, LUBRICANT ADDITIVE AND METHOD FOR PRODUCING SAME, AND LUBRICANT
Document Type and Number:
WIPO Patent Application WO/2024/047952
Kind Code:
A1
Abstract:
Provided is a polymer comprising a structural unit derived from a compound represented by formula (1) and a structural unit derived from a (meth)acryloyl group-containing compound. The content of the structural unit derived from a compound represented by formula (1) is 15 mass% or more in the total of all structural units which is 100 mass%. The weight-average molecular weight of the polymer is 5,000 to 500,000. Also provided is a lubricant additive comprising the polymer and a solvent. (In formula (1), R1 is a group represented by CnH2n+m, in which n is an integer of 1-30, m is -3, -1, or 1, and 2n+m is an integer of 3 or more.)
