  • Patent number: 5739203
    Abstract: This invention discloses a process for applying a rubbery coating to a substrate which comprises: (1) dipping the substrate into a plastisol composition in a manner whereby the plastisol composition is applied to the surface of the substrate, wherein the plastisol composition is comprised of (i) polyvinyl chloride, (ii) from about 70 to about 100 parts of a plasticizer per 100 parts of the polyvinylchloride, (iii) from about 1 to about 3 parts of a stabilizer and (iv) from about 10 to about 30 parts of a highly crosslinked nitrile rubber composition per 100 parts of the polyvinyl chloride, wherein the highly crosslinked nitrile rubber has repeat units which are derived from (a) 1,3-butadiene, (b) acrylonitrile and (c) a crosslinking agent, and wherein said highly crosslinked nitrile rubber has a Mooney viscosity of about 50 to about 120, a swelling index of less than about 10 percent, a mill shrinkage of less than 10 percent and a gel content of greater than 90 percent; (2) removing the substrate from the pla

  • Patent number: 5674933
    Abstract: There is a need for polymers which offer increased heat resistance, ultraviolet light resistance, and low fogging characteristics for utilization in automotive interiors. It is particularly critical for polymers which are utilized in making skin compounds for automotive instrument and door panels to display excellent heat resistance, ultraviolet light resistance, and low fogging characteristics.
