  Synthesis and Characterization of Poly(carbonates) and Poly(thiocarbonates) Derived from Diphenols Containing Silicon as Central Atom

  摘要：

  Poly(carbonates) and poly(thiocarbonates) containing silicon in the main chain and derived from the diphenols bis(4-hydroxyphenyl)-dimethylsilane, bis(4-hydroxyphenyl)-ethylmethylsilane, and bis(4-hydroxyphenyl)-diethylsilane with phosgene or thiophosgene, respectively, were synthesized under phase transfer conditions, using several phase transfer catalysts. Polymers were characterized by spectroscopic methods (IR and H-1, C-13, Si-29 NMR) and the results were evaluated by the yields and the eta(inh) values. In general the effectiveness of the phase transfer process was low, the best results being obtained when the NaOH concentration was increased from the stoichiometric due to a salting-out effect. However, at higher concentrations hydrolytic process were observed. Poly(carbonates) and poly(thiocarbonates) showed, in general, the same trend with the catalysts.
