PRODUCTION OF HYDROCARBON RESINS AND PRODUCTS RESULTING THEREFROM

摘要

Hydrocarbon resins having an increased softening point are obtained by a process featuring the sequential steps of: isomerizing the 2-methylbutene-1 component of a branched olefin modifier stream whereby its 2-methyl-butene-2 content is enriched; polymerizing a feedstock consisting of the mixture of said enriched modifier stream and a piperylene rich feed stream; and, recovering said hydrocarbon resin with properties enhancing its utility for adhesive applications.
