ABSTRACT:
An improvement in the process of incorporating a modifier ingredient into the surface region of a resinous article is described herein. The basic process includes immersing the article in a liquid such as water and contacting the immersed article with a solution of a modifier ingredient in a solvent which is immiscible with the liquid. The improvement herein comprises running the process at a temperature lower than ambient or room temperature whereat substantially no solid material is formed on the surface of the water layer during the process.
