摘要:
This invention relates to a method of forming pressure expressible composition impregnated, microporous resilient articles. In the process of the invention, a microporous article formed from a solvent swellable resilient organic polymeric material is contacted with a mixture of a pressure expressible composition and a solvent swelling agent, capable of swelling the resilient polymer, and having a volatility greater than that of the pressure expressible compositions, to swell the article and enlarge the micropores. The volatile swelling agent is then removed from the article to provide a microporous article containing the pressure expressible composition within the micropores.
