Homopolymers of the diacrylates, dimethacrylates, di(2-haloacrylates) and di(2-cyanoacrylates) of 1-dialkanolaminophospholene-1-oxides and the copolymers of the above esters with lower-alkyl acrylates, meth-acrylates, 2-chloroacrylates and 2-cyanoacrylates are described. These polymers are useful as catalysts in the conversion of organic isocyanates to the corresponding carbodiimides. |
