Determining 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.
