ABSTRACT:
There is disclosed a hydrocarbon derived resin having a structure characterized by a softening point in the range of about 0.degree. C. to about 45.degree. C. and comprising from about 40 to about 80 weight percent units derived from piperylene and correspondingly from about 60 to about 20 weight percent units derived from 2-methyl-2-butene prepared by the method which comprises polymerizng a mixture comprising from about 20 to about 75 weight percent piperylene and correspondingly from about 80 to about 25 weight percent 2-methyl-2-butene in the presence of a catalyst selected from antimony pentafluoride and ferric chloride. The resin has particular utility when combined with rubber as a tackifier to form pressure sensitive adhesives.
