(57) [Summary]nThe present invention relates to a polyurethane elastomer composition comprising a flexible segment obtained from at least one polysiloxane macrodiol and at least one polyether and / or polycarbonate macrodiol, comprising: It relates to a material having processability and / or collapse resistance. This material can function as a collapse-resistant material or a biomaterial, and is particularly useful in the manufacture of medical devices, products or implants that come into contact with living tissue or bodily fluids. The present invention relates to a polyurethane elastomer comprising a soft segment obtained from about 60% to about 98% by weight of at least one polysiloxane macrodiol and about 2% to about 40% by weight of at least one polyether and / or polycarbonate macrodiol. Also provided are compositions and methods of making the same. |
