ABSTRACT:
A process for modifying the surface region of a polymer article by incorporating one or more ingredients therein. Such ingredients may be ultraviolet light stabilizers, antioxidants, anti-static agents, pigments and the like. The polymer article, e.g. a sheet of polyvinyl chloride, is immersed in a liquid (e.g. water) and the immersed article is contacted with a solution of the ingredient in a solvent. The liquid must be one which is non-aggressive towards the article and must also be immiscible with the solvent.
Any residual solution remaining on the contacted surface may be displaced therefrom, preferably by directing a jet of water onto the contacted surface, while avoiding escape of any solvent into the atmosphere.
