Abstract
A novel phosphorylating polycondensation method using phosgene as a ch ain extender was carried out for the first time. Polymers obtained wer e characterized by IR, H-1 NMR, the elemental analysis and copolymers 4 and 5 were further characterized by C-13 and P-31 NMR. The thermal p roperties, (M) over bar(n)s, (M) over bar(w)s, [111] of polymers were investigated. The introduction of phosgene as a chain extender can inc rease substantially the molecular weight of poly(phosphoesters) in sol ution polycondensation. (C) 1997 Elsevier Science Ltd.
