PURPOSE: To obtain an addition polymer which, when cured, can give a rigid durable coating film excellent in wet adhesion and being useful for e.g. a water- based coating material by polymerizing a monomer mixture prepared from a specified aminoalkylimidazolidinone and a compound containing an unsaturation and an epoxy group. n CONSTITUTION: The purpose addition polymer is obtained by polymerizing a monomer mixture containing at least 0.1wt.%, based on the entire weight of the monomer mixture, a polymerizable monomer prepared by reacting a compound represented by formula I [wherein R 1 and R 2 are each a 2 or 3C alkylene; X is H, a 1-18C alkyl or a group of formula II (wherein A and B are each a substituted 2-18C alkyl, provided that at least either of the substituents contains at least one polymerizable ethylenic unsaturation)] (e.g. aminoethylimidazolidinone) successively with 1,2-epoxybutane, glycidyl methacrylate, etc., and represented by formula II. n COPYRIGHT: (C)1990,JPO |
