(57) [Summary] [Objective] To provide a copolymer suitable as an emulsifier for wax. [Structure] Consists of repeating units represented by the following formulas A, B and C, and the molar ratio A: B: C of these units is 10 to 5 A copolymer having a weight average molecular weight of 0:40 to 60: 5 to 40 and a weight average molecular weight of 1,000 to 50,000. Embedded image (In the formula, R is a linear or branched alkyl group having 18 to 98 carbon atoms, R 1 is a linear or branched alkyl group having 2 to 10 carbon atoms, and R 2 is 1 to 3 carbon atoms. Represents an alkyl group or an acyl group, and n represents an integer of 1 to 100.) |
