Abstract
Various poly(monocyclic orthocarbonate)s were synthesized by the polycondensation of 2,2-dichloro-1,3-benzodioxide (1) with a variety of silylated diphenols and their properties were examined. Polycondensation of 1 with silylated Bisphenol A (2) in bulk at room temperature proceeded under the catalysis of HCl or Bu 4 NF to give high yields of the corresponding poly(monocyclic orthocarbonate) (10) but was very slow with catalysts such as Me 3 SiCl, BF 3 OEt 2 , and CsF orwithout catalyst. In bulk polycondensation, 10 (M n =29100) was obtained quantitatively when Bisphenol A (BPA) was used as catalyst, where a quantitative amount of Me 3 SiCl was recovered as a byproduct
