Compositions comprising 15 to 20% amorphous olefin copolymer, 3 to 5% ethene-propene-ethylidine norbornene terpolymer of the sequence type with 25 to 30% propene content, 6 to 8% double bonds, and raw strength 10 MPa, 60 to 82% distilled bitumen, 0 to 3% isotactic polypropylene, 0 to 15% filler and 0 to 1% antioxidizing agent, when heat-sealed to a layer of oxidized bitumen, form a stable bond therewith and thus can be used to form a waterproofing surface coat on fibrous roofing sheets.

Coating compositions for a polymer-modified roofing and waterproofing

Aqueous emulsions of olefin polymers and bitumen comprise:

Aqueous emulsions of polyolefins/bitumen plastic or plastic-elastic

Polymer blends comprising a major amount of polybutene-1 with a minor amount of low-pressure polypropylene or ethylene/propylene or butene-1 copolymers exhibit improved physical properties.
