The main properties of copolycarbonates on the basis of bisphenols of 1,1-dichloro-2,2-di (4-hydroxy-phenyl) ethylene (S-2), 1,1-dichloro-2,2-di (3,5-dibromo-4-hydroxy-phenyl) ethylene (TB-S-2) and dichlorformiate 4,4'-isopropylidenediphenol are synthesized and studied. Regularities of synthesis of copolymers are determined by method of acceptor and catalytic polyfunctional condensation. The interconnection between their composition, structure and properties is also established. It was shown that copolycarbonates exhibited a high softening point and high heat and flame resistance. The existence of the raw material base for the production of the initial monomers, the improved service properties of copolyesters based on them, and the high technological effectiveness of the proposed synthesis method enabled the copolycarbonates to be regarded as industrially promising polymeric materials.
