Synthesis and characterization of aliphatic-aromatic hyperbranched polyesters with high organosolubility

Synthesis and characterization of aliphatic-aromatic hyperbranched polyesters with high... Carboxyl-terminated, water soluble, hyperbranched polyesters (HBPET) with aliphatic-aromatic structure were synthesized at three different monomer mole ratios (A3/B3 = 1: 1, 2: 1, 1: 2, respectively) by melt polycondensation of aconitic acid and phloroglucinol via A3+ B3 approach. Fourier transform infrared (FTIR) spectroscopy indicated as that was expected HBPET, which showed excellent solubility in a variety of polar solvents such as N,N-dimethyl formamide (DMF), N-methyl-2-pyrrolidone (NMP), dimethyl sulfoxide (DMSO), and tetrahydrofuran (THF). The weight-average molecular weight of HBPET ranged from 7792 to 9214 g mol−1 and their intrinsic viscosity were varied from 0.17 to 0.34 dL g−1. The degree of branching of the HBPET was estimated to be 0.44–0.49 by 1H and 13C NMR measurement. The thermogravimetric analysis (TGA) measurement revealed that HBPET was of 10% weight-loss at 340°C in N2. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Applied Chemistry Springer Journals
