| Abstract: | The determination of number average molecular weight of copolyether and mixed polye-ther has been studied by use of 1H-NMR. It can be calculated by measuring the ratio of 1H-NMR absorptions of the relative protons in the polymeric structure to those of -COOCH2/2 and -COOCH ester-H. Agreement with end hydroxy chemical method was observed. |
