SILICONE ACRYLAMIDE COPOLYMER

摘要

The present invention relates to a silicone acrylamide copolymer of high acrylamide monomer content which has transparency and low modulus, employing the following configuration. The copolymer is suitably used for various kinds of medical devices, particularly ophthalmic lenses such as a contact lens, an intraocular lens, an artificial cornea, and is especially suitable for a contact lens. A copolymer comprising (A) a multi-functional (meth)acrylamide monomer having at least one siloxane bond and at least two (meth)acrylamide groups within a molecule and (B) a mono-functional linear silicone (meth)acrylamide monomer.

1. A copolymer formed from a reactive mixture comprising radically polymerizable components comprising (A) a multi-functional (meth)acrylamide monomer having at least one siloxane bond and at least two (meth)acrylamide groups within a molecule and (B) a mono-functional linear silicone (meth)acrylamide monomer of formula (P1)Where Rq comprises a (meth)acrylamide group containing no silicon atom; Ra to Re contain no silicon atoms, and may be independently selected from substituted or unsubstituted alkyl groups having 1 to 20 carbon atoms, or substituted or unsubstituted aryl groups having 6 to 20 carbon atoms, and n represents an integer of 1 or greater.
