FUNCTIONALIZATION OF POLY(PROPYLENE ETHER CARBONATE)DIOLS

Poly(propylene ether carbonate)diols have been functionalized by phosp horylation with dimethyl phosphonate (CH3O)2P(O)H. Two new functional groups P-H and POCH3 have been introduced into the macromolecules. The new functional groups, mainly P-H, allow the phosphorus-contaiing pol y(propylene ether carbonate)s to participate in transesterification, a lkylation (interaction with amines) and dealkylation (interaction with ammonium and metal salts). The structure of phosphorus-containing pol y(propylene ether carbonate)diols is proved by H-1, and C-13-NMR and i .r. spectroscopy and also by elemental analysis for phosphorus.
