  • Patent number: 10920099
    Abstract: The invention is related to a class of hydrophilic poly(meth)acrylamide-based copolymers each comprising dangling (i.e., pendant) reactive chains each terminated with a carboxyl group groups and at least 50% by mole of (meth)acrylamide repeating units relative to all repeating units of the hydrophilic poly(meth)acrylamide-based copolymer. The hydrophilic copolymers have a relatively high affinity to a base coating of a polyanionic polymer on a medical device or contact lens and are highly reactive towards azetidinium groups of an azetidinium-containing polymer upon heating. They can find particular use in producing water-soluble highly-branched hydrophilic polymeric material and in producing water gradient contact lenses.
