Abstract
Novel hydroxyethylnorbornene esters are disclosed which are prepared by reacting cyclopentadienylethanol with an acrylate ester. Novel polyesters are disclosed which are prepared by the self-polymerization of the hydroxyethylnorborane (HEN) esters. Novel polyesters are also obtained by reacting HEN compounds and a diol or other polyol in the presence of diacids or their esters or anhydrides. The polyesters of the present invention are useful as tackifying agents, adhesives, coatings, and for other purposes.
