Glow Discharge Induced Graft Polymerization of Nonvolatile Monomers on Wool

Abstract

Nonvolatile monomers were grafted to wool by exposure to rf glow discharge under vacuum. The amount of grafting was limited to an average of 2 to 5% weight uptake. With increasing impregnation the amount of graft decreased, and mostly extractable homopolymers formed. Increasing the intensity of the glow discharge above a certain level is also detrimental because at this point the rate of degradation exceeds the rate of polymerization.
