Abstract:
A roof structure is disclosed which contains a plastic roofing membrane containing a predominant amount of an internally plasticized vinyl chloride copolymer resin, preferably in combination with a lesser amount of chlorinated polyethylene.
Abstract:
An inherently pliable polymeric marking film comprises a film component containing an internally plasticized vinyl chloride copolymer resin, a layer of pressure sensitive adhesive and, in preferred embodiments, a release coated protective liner. In certain embodiments, the polymeric marking film is destructible. The marking film has a small degree of shrinkage, shows exceptional conformability to irregular surfaces and has permanence of mechanical properties upon exposure to elevated temperatures.
Abstract:
Film forming compositions are disclosed which can be utilized to make vapor barrier films having low water vapor transmission, good flame retardancy and low smoke generation characteristics. The compositions contain an internally plasticized vinyl chloride copolymer resin as a major polymer component, rather than an externally plasticized vinyl chloride polymer, or a blend of a vinyl chloride polymer and chlorinated polyethylene.

Abstract:
Small amounts of a polyurethane elastomer are blended with an internally plasticized vinyl chloride copolymer to improve the abrasion resistance, elasticity, softness or "hand", and low temperature flexibility of films made from the resulting blend. The internally plasticized vinyl chloride copolymer may contain 50 to 80% by weight of vinyl chloride, 3 to 47% by weight of a C 6 -C 10 alkyl acrylate and 47 to 3% by weight of a bis(hydrocarbyl)vinyl phosphonate. The polyurethane elastomer may have a Shore "A" hardness of 69 to 75 and an average particle size of under 1000 micrometers.
Abstract:
A laminate for the protection of motor vehicle bodies from abrasion and corrosion damage which has a film component comprising an internally plasticized vinyl chloride copolymer resin and an effective amount of a polymeric additive for improving the flexibility of the film and an adherent layer of pressure sensitive adhesive.

Abstract:
The use of an internally plasticized vinyl chloride film and a fabric backing, preferably a nonflame retardant fabric backing, as the substrate in a vinyl film/substrate laminate yields a product having a lower rate of smoke generation when burned than is produced by a conventional laminate of an externally plasticized vinyl film and a fabric backing. The internally plasticized vinyl chloride resin used in the vinyl film of the laminate of this invention may be a copolymer comprising from about 50% to about 85%, by weight, vinyl chloride, from about 3% to about 47%, by weight, of a C 6 -C 10 alkyl acrylate, and from about 47% to about 3%, by weight, of a bis(hydrocarbyl)vinylphosphonate. The vinyl film/substrate laminate of the present invention is useful as an upholstery product.
