Abstract
Coated fabrics, for example, are disclosed comprising an open weave substrate (e.g., of polyester resin) coated with an adhesion promoting film comprising a vinyl chloride polymer and a carbon monoxide-propylene copolymer (e.g., having a molecular weight of from about 400 to about 1,000).
Claims8
An article of manufacture comprising:
- (a) a substrate selected from the group consisting of polymer films, yarns, open weave fabrics, and metals;
- and
- (b) an adhesion promoting, fused film comprising a vinyl chloride polymer and a liquid carbon monoxide-propylene polyketone as a plasticizer thereof on the substrate.
