Idzik T J.,(2020) Tailoring the Physico-chemical Properties of Poly(xylitol-dicarboxylate-co-butylene dicarboxylate) Polyesters by Adjusting the Cross-Linking Time”, Polymers (Basel), 12, 1493, doi:10.3390/polym12071493https://hdl.handle.net/20.500.12539/1621Determining the cross-linking time resulting in the best achievable properties in elastomers is a very important factor when considering their mass production. In this paper, five biodegradable polymers were synthesized—poly(xylitol-dicarboxylate-co-butylene dicarboxylate) polymers, based on xylitol obtained from renewable sources. Five di erent dicarboxylic acids with even numbers of carbon atoms in the aliphatic chain were used: succinic acid, adipic acid, suberic acid, sebacic acid, and dodecanedioic acid. Samples were taken directly after polycondensation (prepolymer samples) and at di erent stages of the cross-linking process. Physiochemical properties were determined by a gel fraction test, di erential scanning calorimetry (DSC), Fourier-transform infrared spectroscopy (FTIR), quasi-static tensile tests, nuclear magnetic resonance spectroscopy (1H NMR and 13C NMR), and an in vitro biodegradation test. The best cross-linking time was determined to be 288h. Properties and degradation time can be tailored for specific applications by adjusting the dicarboxylic acid chain length.enUznanie autorstwa 3.0 Polskaester elastomersrenewable sourcescrosslinkingmechanical propertiesbiodegradationDyscyplina::Nauki inżynieryjno-techniczneArticle10.3390/polym12071493
