Abstract
Five‐membered cyclic esters of phosphoric acid of the general formula: CH2CH(R)OP(O)‐(OR′)O polymerize readily to solid, soluble polymers of high molecular weight without any rearrangement known for various tri‐ and pentavalent organophosphorus monomers. 1H‐, 13C‐, and 31P‐NMR spectra of polymers confirmed their linear structure: magnified image where R is H, with R′ = CH3, C2H5, n‐C3H7, i‐C3H7; n‐C4H9, CCl3CH2, or C6H5, or R is CH2Cl and R′ is C2H5. The use of n‐C4H9Li, (C5H5)2Mg, or (i‐C4H9)3Al as initiators leads to polymers with Mn = 104–105.Keywords
