Glycidyl ester and/or use to the coating composition of the copolymer, and that copolymer which are formed from the reaction with the ether and poly- all

摘要

Synthetic method of the copolymer and this copolymer is disclosed. This copolymer glycidyl ester and/or is formed from the reaction with the ether and poly- all which at least contains the functional group 2, this copolymer 50 weight % contains the minimum of the repetitive unit of 3n+X at least here, n is the monomer unit here, and X the monomer unit and/or is the other reactant. In addition as for this copolymer, it can contain the polymer characteristic unit which possesses the same molecular weight less than 50%. This invention furthermore, plans the manufacturing method of this copolymer, and the coating composition which uses this copolymer.
