Abstract
A process for producing a surface-modified molded product of synthetic resin, which comprises contacting a fluorine-containing gas to the surface of a molded product of synthetic resin and then contacting a polymerizable monomer to form a new polymer layer on the surface of the molded product.
Claims6
A process for producing a surface-modified molded product of synthetic resin, which consists essentially of:
- (i) contacting a gas containing fluorine gas in an amount of no more than 20% weight with the surface of a molded product of synthetic resin to form radical reactive sites thereon;
- and then
- (ii) contacting a radical polymerizable monomer with the Alfrey-Price's value e as an index of the reactivity of the monomer being 1.7>e>-1.0 thereto to form a polymer layer having a thickness of from 1 .ANG. to 500 .mu.m initiated by said radical reactive sites on the surface of the molded product.
