Synthesis and Thermal Properties of Polycarbonates Based on Bisphenol A by Single-phase Organic Solvent Polymerization

Abstract

Linear alternating polycarbonates optionally containing bisphenol A were prepared from the reaction of linear aliphatic, substituted aliphatic, cyclic aliphatic and aromatic dihydroxy compounds with bisphenol A bischloroformate at 0–5 °C using a single organic phase as a reaction medium (e.g., Chloroform or tetrahydrofuran). Twelve aromatic–aromatic and aromatic–aliphatic polycarbonate polymers were prepared utilizing this procedure. The effect of the experimental conditions on the polymerization was studied and discussed. The polymers obtained were characterized by IR spectra, 1H and 13C NMR spectra, inherent viscosity, differential scanning calorimetry, and thermogravimetric analyses.
