  The present invention allows the production of a polymerizable hyperbranched polyester by introducing polymerizable unsaturated double bonds into the molecular terminals of a hyperbranched polyester polyol (A), which is obtained by condensation polymerization a polyhydroxy monocarboxylic acid in which there are at least two hydroxyl groups, the carbon atom adjacent to the carboxy group is saturated carbon atom, and the hydrogen atoms on said carbon atom are all substituted, by reacting the hyperbranched polyester polyol (A) and an alkyl ester of a carboxylic acid having a polymerizable unsaturated double bond (B) by a transesterification in the presence of at least one type of transesterification catalyst (C) selected from the group consisting of a dialkyl tin oxide and a stanoxane, without causing side reactions such as nucleophilic addition reactions of terminal hydroxyl groups to polymerizable unsaturated double bonds of the hyperbranched polyester polyol (A), or thermal polymerization of the polymerizable unsaturated double bonds. The polymerizable hyperbranched polyester can be produced at high efficiency using a transesterification that uses as an alkyl ester of a carboxylic acid having a polymerizable unsaturated double bond (B), which is easily obtained as an industrial raw material, and without altering the original backbone structure of the molecular chains of the hyperbranched polyester polyol (A) by hydrolysis and so forth.

  本发明通过在超支化聚酯多元醇（A）的分子端引入可聚合不饱和双键，从而允许生产可聚合的超支化聚酯。超支化聚酯多元醇（A）是通过缩聚至少含有两个羟基的聚羟基一元羧酸（羧基相邻的碳原子是饱和碳原子，该碳原子上的氢原子均被取代）而获得的。在至少一种转酯化催化剂（C）的存在下，通过将超支化聚酯多元醇（A）和具有可聚合不饱和双键的羧酸烷基酯（B）进行酯交换反应，而不引起末端羟基对超支化聚酯多元醇（A）的可聚合不饱和双键的亲核加成反应或热聚合反应等副反应，就可以高效地生产可聚合的超支化聚酯。使用作为工业原料易于获得的具有可聚合不饱和双键的羧酸烷基酯（B）进行酯交换反应，无需通过水解等改变超支化聚酯多元醇（A）的分子链的原始骨架结构。
