| Abstract: | Using the FTIR and 1H NMR methods,the structures,relative ratio and inventory ratio of segmented poly(urea)urethanes which are synthesized with different extenders (1,4 butandiol,ethylene diamine and their mixtures)have been studied successfully and the ratationship between the branch ratio and inventory ratio has been determined. |
