摘要:
A tertiary carboxyl functional polyester resin useful for production of powder coatings is produced by reacting at least one aliphatic compound comprising two aliphatic hydroxyl groups and a tertiary carboxyl group with at least one cycloaliphatic carboxylic acid compound comprising two secondary aliphatic carboxyl groups or the anhydride thereof, wherein each hydroxyl group independently is a primary or secondary hydroxyl group, and wherein the number of hydroxy groups exceeds the number of carboxylic acid groups and anhydrides thereof. The reaction continues until essentially all the non-tertiary carboxyl groups initially present in the reaction mixture have been reacted. These polyester resins may be used together with a suitable curing agent for the production of powder coatings, or may be converted into the corresponding glycidylesters, which in combination with a suitable curing agent can be used for the production of powder coatings.
