Abstract
The present invention relates to polymeric compositions useful in the manufacture of biocompatible medical devices. More particularly, the present invention relates to novel siloxanyl random copolymers bearing polymerizable activated unsaturated end-groups and containing a hydrophilic, cationic substituent in the polymer chain which are capable of polymerization to form transparent polymeric compositions having high water contents; characteristics useful in the manufacture of ophthalmic devices. The polymeric compositions comprises polymerized polymerizable silicone bearing pendant cationic hydrophilic groups
