ABSTRACT:
A composite polymeric material having a high permeability to oxygen is proposed comprising a vinyl chloride moiety, an organosilicon moiety and, optionally, a third polymeric moiety. Such a composite polymeric material can be prepared in several ways including copolymerization of vinyl chloride monomer, a polymerizable organosilicon compound and, optionally, a third monomer, graft-polymerization of a polymerizable organosilicon compound on to a polyvinyl chloride resin, graft-polymerization of vinyl chloride on to an organopolysiloxane, graft-copolymerization of vinyl chloride and a polymerizable organosilicon compound on to a third polymer and blending of the respective polymeric components.
