Effect of dicitrato- and dimalatogermanic acids on polycondensation of maleic anhydride with ethylene glycol

Effect of dicitrato- and dimalatogermanic acids on polycondensation of maleic anhydride with... The catalytic activity of citric (H4Citr) and malic (H3Mal) acids, their coordination compounds with germanium(IV) H2[Ge(HCit)2] and H2[Ge(Mal)2], and germanium dioxide GeO2 in polycondensation of maleic anhydride and ethylene glycol at various temperatures was studied (catalyst: ethylene glycol molar ratio 0.01: 1). The process kinetics was evaluated and the time of its completion was determined. The copolymerization kinetics of some of the prepared oligoesters with triethylene glycol dimethacrylate was studied, and the copolymer properties were determined. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Applied Chemistry Springer Journals
