摘要：

Poly(alkylene hydrogen phosphonate)s with a number-average molecular weight of about 3000 Da were obtained by a transesterification of dimethyl hydrogen phosphonate with poly(ethylene glycol) (PEG 400) under microwave irradiation with a very short reaction time (55 min) relative to that of classical thermal heating (9 h). The structure of the resulting polymer was confirmed by H-1, P-31, and C-13 NMR spectroscopy. The molecular weight was determined by H-1, P-31{H} NMR spectroscopy, MALDITOF, and GPC.
