Abstract
The invention concerns coating composition comprising hydrophobic polymer for use as a photoreactive basecoat for a medical device or implant comprising a polymer made from monomers comprising: (a) 1 to 12 mol % of at least one photoactive monomer that is a hydrogen atom abstracter and (b) 99 to 88 mol % of one or more of acrylamides, methacrylamides, acrylates, methacrylates, and N-vinylpyrrolidone; wherein the polymer has a glass transition temperature (Tg) of less than 40° C.
Claims21
A coating composition for use as a photoreactive basecoat for a medical device or implant, the coating composition comprising a photoreactive hydrophobic polymer made from monomers comprising:
- (a) 1 to 6 mol % of a photoactive monomer comprising a benzophenone moiety, and
- (b) 99 to 94 mol % of one or more of N-vinyl-pyrrolidone, and acrylates and methacrylates of the structure
- where R is an optionally substituted C1-C20 alkyl,
- R′ is either CH3 or H;
- wherein the polymer has a glass transition temperature (Tg) of less than 40° C.
