Abstract
Terpene polymer compositions that have softening points in the range of 0.degree. C. to 85.degree. C. and that are useful as components of hot melt coating compositions, adhesives, and the like, are copolymerized employing from about 20% to 80%, oligomers of cyclic monoterpene hydrocarbons, such as dipentene dimer and/or trimer, and from 80% to 20% of a terpene monomer, such as .beta.-pinene, dipentene or mixtures thereof, said percentages being by weight.
Claims6
A process for the preparation of low softening point resinous terpene polymer having a softening point in the range of approximately 0.degree. C. to 85.degree. C. which comprises:
- polymerizing 20 to 80 parts, by weight, of a terpene hydrocarbon monomer or mixtures of the same with 80 to 20 parts, by weight, of an oligomer of a cyclic monoterpene hydrocarbon in the presence of a Friedel-Crafts catalyst, and recovering a resinous terpene polymer having a softening point in the range of 0.degree. C. and 85.degree. C.
