20130096691 | HYDROPHILIC INTERPENETRATING POLYMER NETWORKS DERIVED FROM HYDROPHOBIC POLYMERS - A composition of matter comprising a water-swellable IPN or semi-IPN including a hydrophobic thermoset or thermoplastic polymer and an ionic polymer, articles made from such composition and methods of using such articles. The invention also includes a process for producing a water-swellable IPN or semi-IPN from a hydrophobic thermoset or thermoplastic polymer including the steps of placing an ionizable monomer solution in contact with a solid form of the hydrophobic thermoset or thermoplastic polymer; diffusing the ionizable monomer solution into the hydrophobic thermoset or thermoplastic polymer; and polymerizing the ionizable monomers to form a ionic polymer inside the hydrophobic thermoset or thermoplastic polymer, thereby forming the IPN or semi-IPN. | 04-18-2013 |
20120277807 | Methods, Devices and Compositions for Adhering Hydrated Polymer Implants to Bone - A method of attaching an implant to a bone, the implant comprising a hydrated polymer comprising a lubricious hydrated surface and an attachment surface comprising accessible chemical functional groups. The method includes the steps of treating the implant or the bone with an isocyanate-containing compound; placing the attachment surface in apposition to the bone; and allowing the isocyanate-containing compound to cure to bond the implant to the bone. The invention also includes a medical implant having a hydrated polymer comprising an attachment surface comprising a thermoplastic material, the hydrated polymer having an interpenetrating polymer network with at least two polymers, the hydrated polymer having a low coefficient of friction on at least one surface. | 11-01-2012 |
