Novel hydrocarbon resins comprising 1,3-pentadiene, 1,5,9-cyclododecatriene and optionally monoolefin |
摘要 |
Hydrocarbon resins comprising about 95-35% by weight of units derived from 1,3-pentadiene, about 1-50% by weight of units derived from cyclododecatriene, and O-about 40% by weight of units derived from at least one monoolefin containing 5 carbon atoms, having a softening point of from about 100 DEG to about 160 DEG C., and being substantially gel-free. The hydrocarbon resins can be prepared by polymerizing a monomeric mixture comprising 1,3-pentadiene in the presence of a Friedel-Crafts type metal halide catalyst, said monomeric mixture comprising about 95-35% by weight of 1,3-pentadiene, about 1-50% by weight of cyclododecatriene, and 0-about 50% by weight of at least one monoolefin containing 5 carbon atoms.
