Abstract

FIELD: polymeric materials. SUBSTANCE: product: statistically branched polycarbonate of the general formula:where R - CHor Rr; R- H or CH; R- - alkyl-group CH-CHor benzyl-group CH-CH; I = 87-95.5 mol.%; K = 6-10 mol.%; p = 0.5-10 mol.%; relative viscosity is 1.170-1.350 measured at 20 C at concentration 0.5 g/100 ml in methylene chloride. Polycarbonate is prepared by interphase polycondensation of corresponding bis-phenols with phosgene in the medium of aqueous alkali and organic solvent, in the presence of branching agent, triethylamine and regulator of molecular mass. EFFECT: improved method of synthesis, enhanced thermostability. 2 tbl
