The hydrogenated bisphenol A polycarbonate prepolymer was synthesized from di-Ph carbonate (DPC) and hydrogenated bisphenol A (HBPA) by melt transesterification in the N2 sweep fluid and low vacuum degree. The prepolymer was analyzed using some simple methods, and its structure was determined by Fourier transform IR spectroscopy, thermal property was determined by differential scanning calorimetry, intrinsic viscosity was determined by ubbelohde viscometer, and appearance of the product was determined by UV-visible spectrophotometer and Ubbelohde viscometer. The structure and properties of hydrogenated bisphenol A polycarbonate (HBPA-PC) prepolymer were compared to that of bisphenol A polycarbonate (BAPC) pre-polymer. The results show that the structure of the polymer indicates that the polymer is polycarbonate. The prepolymer of HBPA-PC have lower than the prepolymer of BAPC in color property, and have higher than the prepolymer of BAPC in the melting temperature under the same synthesis condition in thermal stability and color property. The optimum synthesis conditions are obtained as follows: the dosage of catalyst is 0.00048 mol (1 mol HBPA), the molar ratio between DPC and HBPA is 1.06:1, polycondensation time is 25 min in the range of 170-190°C, polycondensation time is 30 min in the range of 200-220°C. The intrinsic viscosity, the chromatic aberration and the melting temperature of HBPA-PC prepolymer under the optimum conditions are 14.72 mL/g, 2.90, 220.1°C, resp. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Computed Properties of C13H10O3).
Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Computed Properties of C13H10O3
