Reducing electrostatic charge on shaped resin articles surfaces - by exposing to low temp. plasma in nitrogen cpd. atmosphere

摘要

The surface properties of a shaped synthetic resin article are modified by exposing the surface of the article to a low temp. plasma generated in a gaseous atmos. contg. a N-contg. organic cpd. at pressure 0.001-10 Torr; and then opt. contacting it with a halogen or halogen-contg. cpd. The process durably reduces electrostatic charge on the article surface. The use of a PVC resin; ethylamine, allylamine, n-butylamine, methylamine, trimethylamine, dimethylamine, n-propylamine, dimethylformamide, ethylene diamine or pyridine as the N-contg. organic cpd.; and a hydrogen halide or n-propyl fluoride, methyl chloride or bromide, allyl chloride, vinyl chloride or bromide, isopropenyl chloride, 1,1,2-trifluoroethane, 1,1-dichloroethane, chloroform or CCl4 as the halogen-contg. cpd. is claimed.
