Abstract

Abstract A method for the synthesis of polyphosphosiloxane by the thermal condensation of an equimolar mixture of trimethyl phosphate and (3-aminopropyl) triethoxysilane at 200° C was developed. The reaction affords ethanol and polyphosphosiloxane-{Si (OEt)[(CH 2) 3 NR 1 R 2]-OP (O)(OMe)-O} n-(R 1= H, Me; R 2= Me), whose composition and structure were confirmed by 1 H, 13 C, and 31 P NMR spectroscopy, IR spectroscopy, and elemental ...
