## Abstract Surface chemical analysis of two commercially available polyurethanes, i.e., Avcothane and Biomer was carried out by electron spectroscopy for chemical analysis (ESCA). The depth which is subject to analysis is in the range of 50โ€“100 ร…. The variables studied in this study are the differ

Three series of novel polyurethane elastomers containing phenolphthalein as chain extenders were synthesized. The structure of the polyurethane was analyzed using IR and wide-angle X-ray diffraction studies. Tensile strength and percentage of elongation of all the series of polymers were studied. Th

## SYNOPSIS Four series of thermotropic polyurethane elastomers (TPUEs) were synthesized in this study. The hard segments were formed by using 4,4'-methylenedicyclohexyl diisocyanate (H,,MDI) reacted with various mesogenic units, such as benzene-1,4-di(4-iminophenoxyn-hexanol), benzene-1,4-di(4-im
