Syntheses and Characterization of Novel Biostable Polyisobutylene Based Thermoplastic Polyurethanes

Segmented thermoplastic polyurethane elastomers are one of the most important biomaterials. Polyurethanes offer a broad range of physical properties, including high tensile and tear strength, chemical and abrasion resistance, good processibility, and protective barrier properties. However, the polyether soft segment of these polymers is highly susceptible to oxidative degradation. Polyisobutylene (PIB) is well known for its superior biostability and biocompatibility. This presentation will explore the synthesis, processing, mechanical properties and biostability of novel PIB based polyurethanes.
