Abstract
There is disclosed the preparation of an alpha-olefin-sulfur dioxide copolymer derived from the C.sub.8 to C.sub.18 alpha-olefins. The polymers undergo clean thermal degradation, having high permeabilities to oxygen and carbon dioxide, and are readily processed into a membrane article. Maximum permeabilities are obtained with the C.sub.16 based polymer. New uses of the copolymer are set forth including perfusion membranes, soft contact lenses and biocompatible articles for contact with human body fluids including surgical tubing, wound dressings, and prosthetic devices such as artificial veins, arteries and heart valves.
