ACRYL POLYMER HAVING POLYMERIZABLE UNSATURATED GROUP AT MOLECULAR TERMINAL

摘要

PROBLEM TO BE SOLVED: To provide an acryl polymer wherein a polymerizable unsaturated group is certainly incorporated to the molecular terminal, the emulsifier or dispersant or the like are not contained and solvent compound residues and known initiator residues such as azo and peroxide are no present at the molecular terminal. SOLUTION: The acryl polymer having the group at the molecular terminal is obtained by the reaction of an acryl prepolymer with the number average molecular weight of >=500 and <=100,000 by GPC which is obtained by the bulk polymerization of a polymerizable monomer having (meth)acrylic acid alkyl ester as a main component using a compound having a thiol group and carboxyl group within the molecule as a polymerization initiator under an inactive gas atmosphere and a compound having a hydroxyl group and a polymerizable unsaturated group within the molecule or a compound having an epoxy group and a polymerizable unsaturated group within the molecule.
