(2020)” Effect of E-Beam Irradiation on Thermal and Mechanical Properties of Ester Elastomers Containing Multifunctional Alcohols” Polymers (Basel), 12, 1043, doi:10.3390/polym12051043https://hdl.handle.net/20.500.12539/1619The 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).enUznanie autorstwa-Użycie niekomercyjne-Bez utworów zależnych 3.0 PolskaUznanie autorstwa 3.0 Polskaester elastomerssugar alcoholse-beam irradiationmechanical and thermal propertiesDyscyplina::Nauki inżynieryjno-techniczneArticle10.3390/polym12051043
