Abstract
It is herein disclosed a novel elastomeric polybutylene-1 having and exhibiting syndiotacticity of greater than ten percent, and possessing other desirable properties. The novel elastomeric polybutylene-1 can be blended with compatible materials such as polypropylene and its copolymers, ethylene-propylene block copolymers, butyl rubbers and polyisobutylene. Such compositions are particularly suitable in films, hot melt adhesives, textile and fiber applications. The novel elastomeric polybutylene-1 can also be blended with incompatible materials such as ethylenically unsaturated esters (EVA, EMA, EMAA, EEA), polyester, nylon, polystyrene, styrene block copolymers (SEBS, SIS, SBS) and polyethylenes into a composition having soft and improved elastic properties. Such blends are particularly useful in easy-open packaging and foam applications, and in PVC replacement. When oriented, films made of such blends are used as soft and elastic shrink films. The novel elastomeric polybutylene-1 can also be blended with both incompatible and compatible materials.
