Process for producing polymerizable polybranched polyester |
| abstract |
A polybranced polyester polyol (A) obtained by condensation-polymerizing a polyhydroxymonocarboxylic acid which has at least two hydroxy groups and in which the carbon atom adjacent to the carboxy group is a saturated carbon atom and all of the hydrogen atoms on the carbon atom have been replaced and an alkyl ester (B) of a carboxylic acid having a polymerizable unsaturated double bond are subjected to transesterification in the presence of at least one transesterification catalyst selected from the group consisting of dialkyltin oxides and stannoxanes. Thus, a polymerizable polybranched polyester having the polymerizable unsaturated double bond incorporated at a molecular end of the polybranched polyester polyol (A) is highly efficiently produced without causing a nucleophilic addition reaction between a terminal hydroxy group of the polybranched polyester polyol (A) and the polymerizable unsaturated double bond or side reactions such as thermal polymerization of the polymerizable unsaturated double bond. |
