摘要

PROBLEM TO BE SOLVED: To provide a polymer capable of providing a paste having excellent thixotropy property, no stringiness or bleeding during printing, and excellent thermal decomposition property. SOLUTION: The molar ratio of the monomer (A) represented by the formula (1) is 10 mol% to 100 mol%, and the molar ratio of another monomer (B) copolymerizable with the monomer (A) is 0 to 0. A polymer having a weight average molecular weight of 90 mol% and a weight average molecular weight of 10,000 to 1,000,000. (Chemical formula 1) (R1 represents a hydrogen atom or a methyl group, R2 represents an alkyl group having 1 to 18 carbon atoms or a hydroxyalkyl group having 1 to 18 carbon atoms, and A represents an alkyl group having 1 to 18 carbon atoms and 10 or less carbon atoms. Indicates an alkylene group of, X indicates 0 or 1, and Y1 is one or more structures selected from the group consisting of hydroxyurethane structures of the formulas (2) and (3).) [Selection diagram] None.
