Abstract
A novel product of the polymerization of butene-1 is highly stereoregular but nevertheless has low crystallinity and has properties of a thermoplastic elastomer. This elastomeric polybutylene is the total product. Its elastomeric qualitites lie between those of plasticized vinyl polymers and conventional vulcanized rubbers. The butene-1 polymers may be compounded with extenders and fillers for use as molded or extruded elastomeric product or may be used without plasticizer addition in place of flexible vinyl polymers, such as highly plasticized poly(vinylchloride) PVC.
