ABSTRACT:
Novel heat-curable elastomeric polymers are produced which comprise an elastomeric base polymer modified by the presence on the elastomeric base polymer molecule of at least one pendant carboxylic acid ester group wherein the ester moiety is alkyl arylcyclobutene. In a preferred embodiment, the base polymer is a selectively hydrogenated block copolymer of the poly(vinylaromatic compound)/polyalkadiene type, and the ester moiety is methylbenzocyclobutene.
