摘要：

New segmented polyurethanes containing in the chain extender molecule (dihydroxyethyl-n-hexadecylamine, DHHA) both a hydrophobic long alkyl group and a tertiary ammonium group (whose polarity was further increased by quaternization reaction), are described. In order to evaluate the influence of the chain extender content on the polymer properties, also polymers containing DHHA and 1,4 butanediol at different molar ratios have been prepared. The obtained polymers were characterized by i.r., NMR, DSC, viscometry and water swelling measurements.
