Abstract
Poly(carbonates) derived from diphenols that contain Si or Ge and bisphenol A bis(chloroformate) have been synthesized using phase-transfer conditions. The products were characterized by spectroscopic methods. Two phase-transfer catalysts and three molar ratios of NaOH/diphenol were used. The results were evaluated by the yields of product and their inherent viscosities. The data were compared with materials obtained without the catalyst and showed that the new synthetic technique was effective for the synthesis of these types of poly(carbonates). An increase in the concentration of NaOH and the phase-transfer catalysts increased the yields and ηinh values compared to those obtained with stoichiometric quantities of NaOH. It is proposed that the differences in electronegativities of the heteroatoms in the diphenols are responsible for this behaviour.
