Document Type and Number:
WIPO Patent Application WO/2005/056512
Kind Code:
A1
Abstract:
A process for the production of adamantyl esters of polymerizable unsaturated carboxylic acids which is characterized by comprising the esterification step of reacting a mixture of a polymerizable unsaturated carboxylic acid and a polymerizable unsaturated carboxylic acid anhydride with an adamantanol in the presence of an acid catalyst and a polymerization inhibitor. According to the process, the formation of oligomeric impurities as by-products is remarkably inhibited.
