Patent ID: 8524884

Claim:
A material comprising: (i) an outer layer comprising an entanglement; and (ii) a hydrophilic outer surface of said outer layer, wherein said entanglement comprises a physical blend of a hydrophobic polymer host and an anhydride functionalized hydrophobic polymer co-host, and a hydrophilic guest; wherein said hydrophobic polymer host comprises a polyolefin; wherein said anhydride functionalized hydrophobic polymer co-host comprises a polyolefin which has been functionalized with anhydride functional groups; wherein said hydrophilic guest comprises hyaluronic acid; and said entanglement having been synthesized by: (a) intermingling cloaked hydrophilic guest complexes with said physical blend of said host and said co-host; (b) crosslinking molecules of said guest with said guest; and (c) performing a hydrolysis reaction.
