The aim of this work was to investigate the thermal and mechanical properties of novel,
electron beam-modified ester elastomers containing multifunctional alcohols. Polymers tested in this
work consist of two blocks: sebacic acid–butylene glycol block and sebacic acid–sugar alcohol block.
Di erent sugar alcohols were utilized in the polymer synthesis: glycerol, sorbitol, xylitol, erythritol,
and mannitol. The polymers have undergone an irradiation procedure. The materials were irradiated
with doses of 50 kGy, 100 kGy, and 150 kGy. The expected e ect of using ionizing radiation was
crosslinking process and improvement of the mechanical properties. Additionally, a beneficial side
e ect of the irradiation process is sterilization of the a ected materials. It is also worth noting that
the materials described in this paper do not require either sensitizers or cross-linking agent in order
to perform radiation modification. Radiation-modified poly(polyol sebacate-co-butylene sebacate)
elastomers have been characterized in respect to the mechanical properties (quasi-static tensile
tests), cross-link density, thermal properties (Di erential Scanning Calorimetry (DSC)), chemical
properties: Fourier transform infrared spectroscopy (FTIR), and wettability (water contact angle).
Poly(polyol sebacate-co-butylene sebacate) preopolymers were characterized with nuclear magnetic
resonance spectroscopy (1HNMRand 13C NMR) and gel permeation chromatography (GPC). Thermal
stability of cross-linked materials (directly after synthesis process) was tested with thermogravimetric
analysis (TGA).
