摘要：

Structures of alpha,omega-dihydroxy polyethers and copolyethers were investigated extensively using H-1 and C-13 NMR spectroscopy and mass spectrometry (electrospray ionization technique). The H-1 NMR study was achieved from samples of which the hydroxy end groups were modified with trifluoroacetic anhydride. In particular, the nature of end groups (primary or secondary hydroxy end group), the accurate chemical structure and the molar mass of copolyethers were determined.
