ABSTRACT:
Plasma polymerization of a fully alkylated disiloxane is greatly enhanced by the addition of oxygen to the plasma feed gases. Deposition rate of polysiloxane polymerizate upon substrates is increased, and the deposits are nontacky. Composite permselective membranes made by deposition of plasma-polymerized polysiloxanes in the presence of oxygen are useful for applications such as gas separations. Composite hollow fiber membranes of polysiloxane polymerizate on porous polypropylene exhibit oxygen
itrogen permselectivities greater than 2.3 combined with increased oxygen permeability.
