ABSTRACT:
A non-crosslinked crystallized polymer or polymer blending coating is disclosed for articles that come into contact with bodily fluids. The polymer or polymer blend to be used is crystallizable and is stable in the presence of water at temperatures of up to about 60.degree. C. when in the crystalline state. The polymer or polymer blend is dissolved in a solvent, such as water or dimethyl sulfoxide (DMSO), and is coated on the article. The polymer coating is then crystallized, generally by heat treatment, providing both toughness and increased adherence of the coating to the article without ready dissolution when the article comes into contact with fluids.
