摘要:
The equilibrium association of urethane groups in a series of 4,4'-diphenylmethane diisocyanate/poly-(propylene oxide)-based poly(ether urethane) elastomers was studied on the basis of infra-red spectroscopy data. Thermodynamic parameters of the urethane-group association were estimated. The hard-segment equilibrium state was shown to fit a model of monomer solution association.
