Glycidyl ester adducts having increased glass transition temperatures

摘要

The invention provides for a purified glycidyl ester product prepared from neo acids wherein said ester product is recovered as a light fraction from a glycidyl ester reaction product composition that has been subjected to conditions of temperature and vacuum in a thin film, short pass distillation evaporator, said purified glycidyl ester product further characterized that its polymerizable reaction product with methacrylic acid has a higher effective glass transition temperature as compared with the polymerizable reaction product with methacrylic acid of said glycidyl ester reaction product composition prior to purification.
