Abstract
The aim of this work was synthesizing ester elastomers, using sorbitol as a
monomer obtainable from renewable sources. Three polymers were synthesized, utilizing three
di erent polycondensation times. Their mechanical and thermal properties were examined and
compared. Poly(sorbitol sebacate-co-butylene sebacate) elastomers were synthesized as a result
of polycondensation reaction, using sebacic acid, butylene glycol and sorbitol as monomers.
Resulting materials had good mechanical properties and a cross-linked structure. Such elastomers
are susceptible to hydrolytic degradation which has been confirmed in earlier studies. This paper
shows that the material synthesized utilizing a 3.5 h polycondensation time has the most desirable
mechanical and thermal properties, and the reaction is characterized by the highest degree of
conversion of substrates.
