The photocurable resin is retained in a base material to form a support material. The inner side of the support material is covered with a buffer material and the outer side thereof is covered with a cover material to obtain a splint material as a fixture for orthopedic surgery. The buffer material side of the splint material is put on an affected part of the body and a bandage is wound over it, and then molding is carried out using irradiation with visible light to cure the photocurable resin. As the curing proceeds, a splint is obtained for fixing and supporting the affected part. | 10-22-2009 |

| 20090306240 | PROCESS FOR SYNTHESIS OF TELECHELIC URETHANE ACRYLATE UV CURABLE PRE-POLYMERIC MATERIALS - The present invention involves the design of a radiation curable organic pre polymer resin material based on urethane acrylic linkage synthesized from the natural renewable resource cardanol or a derivative thereof, for coating application. These new molecules have a faster and better curing rate compared to the starting renewable resource—cardanol. This is brought about by the hydrogen bonding of the urethane linkage which leads to a pre organization of the molecules in such a way as to bring the cross linkable double bonds closer to each other. The present invention also involves a UV curable formulation of the above mentioned resins along with 2-10 parts by weight of a photopolymerization initiator. The resin, either in a formulation or alone turns into a cross linked film upon photopolymerization in presence of photoinitiator under a UV curable radiation source like a mercury vapor pressure lamp. | 12-10-2009 |
