Polyesters and a process for preparing these polyesters

Abstract

The present invention relates to a polymer comprising units derived from a carboxylic two OH-groups, wherein the alcohol comprising at least two OH-groups is a bi-cyclo-aliphatic diol of formula (IX) with R1=ethyl, —CH2—CH2—CH2OH, or —CH(—CH3)—CH2OH, and R2═H or —CH2OH, with the proviso that R2 is not H when R1=ethyl, to a process for preparing a polymer by reacting at least one carboxylic acid comprising at least two carboxylic groups or its anhydride or ester and at least one alcohol comprising at least two OH-groups, wherein the alcohol comprising at least two OH-groups used is a bi-cyclo-aliphatic diol of formula (IX), and to the use of a polymer according to the invention or obtained by a process according to the invention as or for the production of lacquers, coatings or adhesives, preferably tube or can coatings, metal decorating enamels, heat sealing lacquers, hot laminating adhesives, or primers.
