Synthesis of Hydrolysis Resistant Polyisobutylene-Based Polyurethanes

This paper will discuss the synthesis of  polyurethanes using a polyisobutylene-based diol as one of the reactants. It has been shown that incorporation of polyisobutylene into polyurethanes increases the hydrolytic stability. We have developed a process that produces a very clean polyisobutylene-based diol with precise functionality using living polymerization. We plan to use the resulting polyurethanes for electrospinning drug eluting rubbery fiber mats for biomedical applications.
