Abstract
A composition and process for modifying the surface region of a polymer article. The composition is a mixture of a resin surface modifier ingredient, a resin-swellable organic solvent and a surfactant additive. The composition is contacted with the surface of a resin article, while the article is immersed in a liquid which may also contain a surfactant which is non-aggressive toward the article and immiscible with the solvent. The surfactant alters the wetting characteristics of the air-liquid, or liquid-surface modifier interfaces, or both interfaces, so that a film of the modifier ingredient does not form on the surface of the liquid layer.
