A series of hard-segment model compounds based on 3,5-diethyltoluene diamine,4,4'-diphenylmethane diisocyanate and phenyl isocyanate has been synthesized in this paper.The model compounds are microcrystals.Combined with WAXD analysis,the assignment of the bands at 1643 cm(-1)and 3290 cm(-1)in the FTIR spectra of the model compounds is given.Both bands are the hydrogen-bonded urea carbonyl and urea NH groups with the form of planarly bifurcated hydrogen bonds in the microcrystals,respectively.Melting points of the model compounds are almost the same as the change of average degree of polymerization by DSC experiments.
