ABSTRACT:
There are provided .alpha.-pinene epoxide polymers and .beta.-pinene epoxide polymers prepared by polymerizing monomeric .alpha.-pinene epoxide or .beta.-pinene epoxide dissolved in a non-polar solvent at a temperature ranging from between about -20.degree.C. and about -150.degree.C. in the presence of an inorganic, nonmetallic, fluoride catalyst, such as boron trifluoride and phosphorous pentafluoride, to obtain an optically active polymer useful as a tackifier in an adhesive composition.
