Segmented polyurethanes are an important class of thermoplastic elastomers
which have potential use as a biomaterial. Biostability, biocompatibility and
some other features of polyurethanes can be improved by the introduction of
poly(dimethylsiloxane) in the polymer chain. A series of novel
thermoplastic polyurethanes was synthesized by two-step polyaddition
reaction in solution from 4,4′-diphenylmethane diisocyanate (MDI), 1,4-
butanediol (BD) and poly(propylene oxide)-b-poly(dimethylsiloxane)-bpoly(propylene oxide) (PPO-PDMS). The content of PPO-PDMS (i.e. soft segment) was varied between 40 and 90 wt%. The influence of PPO-PDMS content on the structure and thermal properties of copolymers was
investigated by FTIR, 1H and 2D NMR spectroscopy, as well as by DSC
analysis.
