摘要：
Stress relaxation of two poly(ether-urethane-urea)s was monitored using FTIR spectroscopy. Structurally, these block copolymers were the result of the reaction of 1 mol of a polyol [poly(propylene glycol) or poly(tetramethylene glycol)], 2 mol of 4-4'-dihexylmethane diisocyanate, and 1 mol of propylenediamine. FTIR spectra during relaxation showed that the copolymer based on poly(tetramethylene glycol) is more phase-segregated then the one based on poly(propylene glycol). (C) 1999 Elsevier Science Ltd.
