| titleOfInvention | Method for producing polymerizable hyperbranched polyester |
| abstract | SOLUTION: A hyperbranched polyester polyol (A) and a carboxylic acid alkyl ester having a polymerizable unsaturated double bond (B) are transesterified in the presence of a transalkylation catalyst (C) comprising dialkyltin oxide or stannoxane. And a transesterification reaction to introduce a polymerizable unsaturated double bond into a molecular terminal of the multi-branched polyester polyol (A). [Effect] Using an easily available carboxylic acid alkyl ester (B) as an industrial raw material, with high efficiency, causing a nucleophilic addition reaction or a side reaction such as thermal polymerization of the polymerizable unsaturated double bond. In addition, a polymerizable multibranched polyester can be produced without changing the basic skeleton structure of the molecular chain of the multibranched polyester polyol (A) by hydrolysis or the like.
