Abstract
PURPOSE:To prepare a colorless, phosphorus-containing high polymeric polyester with simple reaction procedures, without corroding the reaction apparatus, by reacting a phosphorus halide with a bisepoxide compound in an inert solvent in the presence of a catalyst. CONSTITUTION:A phosphorus-containing polyester of formula III (n is 1-50) is preapred by reacting a phosphorus halide of formula I (Y is R1O, R1; R1 is aryl, halogen-substituted aryl, 1-7C alkyl, halogen-substituted alkyl; X is halogen; the halogens are Cl or Br) with a bisepoxide compound of formula II (R2 is a di- functional group selected from arylene, halogen-substituted arylene, alkylene and/or halogen-substituted alkylene) in an inert solvent, in the presence of a catalyst, at -50-+200 deg.C.
