ABSTRACT:
A porous article is prepared by subjecting a substantially non-porous polymeric shaped article containing from about 1.0-30% of plasticizer to a plasma treatment under conditions such that the plasticizer is volatilized or decomposed into gaseous decomposition products thereby creating an internal pore structure while leaving the surface of the article essentially intact and free from microscopically visible pores.
