Page/Page column 8; 9, (2017/07/14)
A process for producing an oligomer comprising contacting a dialkyl carbonate and a dihydroxy compound in a reaction zone in the presence of an oligomerization catalyst under oligomerization conditions to form the oligomer wherein the molar ratio of dihydroxy compound to dialkyl carbonate in the reaction zone is at least 2:1.

The reactive polycarbonate precursors of phenyl carbonate-ended oligomers amenable to polycondensation in the phosgene-free polycarbonate process were catalytically synthesized via a novel one-step reaction of the coupled oxidative carbonylation of bisphenol-A and phenol with carbon monoxide.
