AMPHIPHILIC COPOLYMER COMPOSITIONS

摘要

The present invention provides an amphiphilic coating material for applying on at least a portion of one surface of an article. The amphiphilic coating material comprises a copolymer containing one or more alkyl methacrylate or alkyl acrylate co-monomer units; one or more vinyl acetate co-monomer units; and up to 40% mole of polyethylene oxide substituted methacrylate co-monomer units. Optionally, one or more biologically active molecules may be covalently bonded to the polyethylene oxide substituted methacrylate co-monomer units. The present invention also provides an article having the inventive amphiphilic coating thereon.
