Abstract

The preparation of uniform thin films of polyurethane and the changes in the carbonyl and amine spectral envelopes were discussed. The MDI-BDO hard segment of the polyurethanes was found to be maintained at a weight fraction of 40%. At least two sets of hydrogen bonding changes occurred as the weight fraction of polydimethylsiloxane (PDMS) macrodiol was increased. Analysis shows that the changes reflect increased ordering in the inter-domain and hard segment domains with increased fraction of α, ωPDMS.
