摘要:
Methods for preparing functionalized polyvinylpyrrolidones with polymerizable functions. Also, amphipathic polydimethylsiloxane-PVP block copolymers, such as and (meth)acrylated and (meth)acrylamide-functionalized polyvinylpyrrolidone compounds, such as The block copolymers are useful as biomaterial components in biomedical devices. They provide improved wettability, lubricity, and material compatibility to the biomedical device, e.g., ophthalmic lenses.
