Using the characteristic peaks in H-spectra for the different functional groups of ethyle-ne terephthalate-caprolectone segmented copolymer

We have calculated and proved that two kinds of the intensity formulas reflect the quantitative relationships of the coresponding functional groups in the hard and soft segments

and the chemical structure of the chain is confirmed.On the basis of this

utilizing the contribution of the different functional groups to their characteristic peaks in H-spectra

the formulas for the number of soft and hard segments

for the average length and molecular weight of the soft and hard segments and for the con-tent of the hard segents have been found directly. The H-spectra and C-spectra have been analysed by the method of the probability of the triad and the result reconfirmed the chain structure of segmented copolymer that we got be-fore.
