Abstract: Novel heat-curable compositions are obtained by combining a bis(2-hydroxyethyl)dicyclopentadiene containing polyester and an unsaturated polyester. These compositions can be cross-linked by heating at temperatures above 135.degree. C., and do not require cross-linking agents or radical initiators. The compositions of the present invention are useful as coatings and adhesives having superior qualities.

Abstract: Novel hydroxyethylnorbornene esters are disclosed which are prepared by reacting cyclopentadienylethanol with an acrylate ester.

Abstract: Novel esters and polyesters are prepared by reacting cyclopentadienylethanol, bis(2-hydroxyethyl)dicyclopentadiene, or mixtures of the two with monobasic acid esters and dibasic acid diesters. These esters and polyesters are characterized by a reversible cross-linking mechanism and have utility as superior coatings and adhesives. High molecular weight, cross-linked polymers are also prepared in the present invention by reacting cyclopentadienylethanol with a polyolefin wax having an ester, acid or anhydride functional group.

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.

Abstract: The present invention provides a process for the preparation of low molecular weight polyesters directly from hydroxypivaldehyde. The process comprises reacting dry hydroxypivaldehyde with a diester, a multifunctional ester, a diacid, a polyester, or a mixture thereof at a temperature of about 100.degree. C. to 230.degree. C. in the presence of a transesterification catalyst. Optionally, modifying glycols, triols, or polyols may also be added. Suitable catalysts include tetraisopropyl titanate, dibutyltin oxide, lithium hydroxide, and lithium alkoxide, with tetraisopropyl titanate being especially preferred. The reaction is preferably accomplished in two stages by heating the reaction mixture to about 130.degree. C. for about three hours and subsequently heating the reaction mixture to about 190.degree.-230.degree. C. until the reaction is essentially complete.

Abstract: This invention relates to an improved method for the catalyzed condensation of aldehydes in the liquid phase to form 1,3-glycol monoesters utilizing tin metal or a tin oxide catalyst. Condensation can be visualized as an aldol condensation followed by a Tischenko reaction between the aldol and a third molecule of aldehyde. In its simplest form the condensation can be illustrated by the following general formula ##STR1## R or R.sup.1 =Hydrogen or alkyl group of 1 to 20 carbon atoms or aromatic groups. R and R.sup.1 can also be part of a cyclic system.
