Abstract
Polyphosphonate esters of molecular weights similar to 10(4) were synthesiz ed by base promoted liquid-vapor polycondensation of cyclohexylphosphonic d ichloride with bisphenol A. The effect of temperature, reaction time, base concentration and molar ratio of reagents on yield, inherent viscosity and molecular weight of the obtained polymer was studied. A second order, centr al composite, rotatable experimental design was used to find domain experim ental field for optimal yields and high inherent viscosities.
