Abstract：

Polyurethane　was　synthesized　by　the　reaction　of　isophorone　diisocyanate,　2-hydroxyethyl　methacrylate　and　diethylene　glycol.　Then　polyurethane　grafted　calcium　alginate　gel　material　was　prepared　via　free-radical　grafting　polymerization　with　azobisisobutyronitrile　as　an　initiator.　Modified　calcium　alginate　hydrogel　was　improved　in　thermal　property,　crystallinity　and　anti-swelling　properties.　The　reason　is　that　polyurethane　side　chains　affect　the　arrangement　of　calcium　alginate　by　forming　highly　ordered　crystal　region.　©　2014　Elsevier　B.V.
