摘要:
Methods of impregnating various polymer substrates with an impregnation additive, by simultaneously contacting the polymer substrate with an impregnation additive, carrier liquid, and supercritical fluid are provided. The impregnation additive is substantially insoluble in the supercritical fluid, and the carrier liquid is preferably substantially insoluble in the supercritical fluid.
摘要:
Foamed thermoplastic articles, both filled and unfilled foamed articles have a foamed density of greater than 0.03 grams per cubic centimeters (g/cm.sup.3), cell sizes in the range of 10 to 300 micrometers (.mu.m) with cell wall thicknesses of greater than 0.1 .mu.m but less than 2 .mu.m and a process for making the same.
