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 removing a substantial amount of air dissolved in the water layer to prevent droplets of solution from rising to the surface of the water layer during the process, thereby preventing solid modifier material from accumulating on the water surface.
