Abstract

A composition comprises a blend of polyisobutylene and from 5 to 50% of the blend of amorphous linear polypropylene. The polyisobutylene has a molecular weight of 150,000 to 300,000 and the polypropylene of 2000-100,000. The polypropylene is prepared by the low pressure process. Antioxidants and stabilizers e.g. N-lauroyl-aminophenol, phenylbetanaphthylamine and bisphenol type stabilizers may also be present. Specification 810,023 is referred to.
