| Summary: | Abstract Hitherto unreported aromatic polyorthocarbonates have been synthesized by the reaction of dichlorodiphenoxymethane and various aromatic dihydroxy compounds. magnified image The polymers possess the structure of a methanetetra‐ol ether (carbonic acid orthoester) in the main chain. The direct structural evidence was obtained by 13 C NMR. High molecular weight, linear polyorthocarbonates were derived from sterically unhindered bisphenols. The polymers were noncrystalline, and clear, flexible films were obtained by casting from solution. Aromatic polyorthocarbonates decomposed above 360°C under nitrogen. The polymers were extremely stable under basic conditions but were unstable in strongly acidic media, particularly at elevated temperatures. |
