Japanese Patent JPS571542
Kind Code:
B2
Abstract:
A novel method is proposed for preventing bleeding of plasticizers on the surface of shaped articles of plasticized polyvinyl chloride resins. The method comprises blending a limited amount of an organosilane compound represented by the general formula CH2=CR1-CO-O-CH2)a Si(R2)b(OR3)3-b in which R1 and R3 are each a hydrogen atom or an alkyl group, R2 is a monovalent hydrocarbon group, a is an integer from 1 to 6 and b is a number of 0, 1 or 2 with the polyvinyl chloride resin prior to fabrication of the resin into shaped articles, fabricating the resin admixed with the organosilane compound into a desired shaped article, and subjecting the shaped article to a treatment with low temperature plasma of a gas. Carbon monoxide is preferred as the gas for plasma atmosphere.
