TAGLE, L.H.; TERRAZA, C.A.; AHLERS, W.  y  VERA, C.. SYNTHESIS OF CONDENSATION POLYMERS DERIVED FROM SILYLATED MONOMERS UNDER PHASE TRANSFER CATALYSIS. J. Chil. Chem. Soc. [online]. 2005, vol.50, n.3, pp. 535-539. ISSN 0717-9707.  doi: 10.4067/S0717-97072005000300002.

The synthesis of the poly(carbonate) and poly(thiocarbonate) derived from the diphenol bis(4-hydroxyphenyl)-phenylmethylsilane and the poly(ester) derived from the same diphenol and the acid dichloride bis(4-chloroformylphenyl)-phenylmethylsilane are described. Polymers were synthesized under phase transfer conditions and the results were evaluated by the yields and inherent viscosity values. The phase transfer process was effective, but the results were affected by the increase of the NaOH concentration in the aqueous phase, in the sense that it was possible to see hydrolytic processes that decrease the yields and the inherent viscosity values. Also there was an influence of the nature of the catalysts, with BTEAC being efficient due to it hydrophilic nature
