The research progress about hydrogen bonding of polyether poly(urethane urea)s was reviewed in this paper with 29 references.
简要评述了近年来有关聚醚型聚氨酯脲氢键研究进展。
The results can be explained in terms of better phase separation and higher melting temperatures of the urea linkages over the urethane linkages.
这可用脲键比氨酯键有较好的相分离和较高的熔化温度来说明。
