Disclosed is a surface-modified polymer composition formed from an oligomeric or polymeric additive and a base polymer. Surface modified polymers provide non-fouling and / or non-thrombogenic properties. The compositions are particularly useful in articles and materials for medical applications. The disclosed techniques include: i) zwitterionic monomers or polyalkylene glycol monomers; ii) silicone or fluorocarbon monomers, or combinations thereof; or iii) alkyl substituted methacrylate, acrylate, acrylamide, or vinyl monomers, or these A surface-modified additive composition is provided comprising an oligomeric or polymeric additive formed from two or more of the combinations. |
