Abstract

Soft polyurethane films are ideal for use in medical products as a backing film for scaffold devices. Two series of polyesterurethanes (PEUs), synthesized from polyethylene adipate diol (PEA) and polycaprolactone diol (PCL), both with Mn of 2000 g/mole, diphenylmethane diisocyanate (MDI), and ethylenediol (ED) or diethylenediol (DED) in combination with glycerine (Gly) as chain extenders, were analysed in this study. The effect of the hard and soft segments concentrations, polyols nature and chain extender structures on the polymers has been discussed with respect to thermal, mechanical and wetting properties. By rigorous selection of the polyurethane matrix, it is possible to obtain polymers with great potential of advanced materials..
