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.

Abstract: The present invention provides a relatively low molecular weight polymer comprising units derived from an unsaturated dicarboxylic acid and units derived from octadienol. The polymer exhibits a fluid viscosity of at least about 200 cp when measured in the neat state at room temperature using a Brookfield viscosimeter. The unsaturated dicarboxylic acids from which the polymer units are derived include fumaric acid, maleic acid, and mixtures thereof. The octadienol from which the polymer units are derived commonly comprises a mixture of 2,7-octadien-1-ol and 1,7-octadien-3-ol. Preferably, the polymer exhibits a fluid viscosity of about 700-900 cp. The process for preparing the polymer comprises reacting octadienol with an unsaturated dicarboxylic acid selected from fumaric acid, maleic acid, lower alkyl diesters of said acid, and mixtures thereof in the presence of an esterification catalyst. Preferably, the esterification catalyst comprises dibutyltin oxide and is present in an amount of about 0.
