ABSTRACT:
Blends of chlorosulphonated polyethylene and defined bituminous material are modified by the addition of not more than 15% by weight, based on total weight of chlorine-containing synthetic elastomer, of a thermoplastic olefin polymer having a softening point in the range 110.degree.-160.degree. C. The incorporation of this polymer reduces shrinkage when sheets formed from the blend are exposed to heat while in use.
