Frost-Resistant Polyurethane-Urea Materials Based on Oligoethers

Resumo

Physicomechanical behavior of cross-linked segmented polyester urethane ureas with poly(tetramethylene oxide) segments of varied molecular mass, plasticized with di-(2-ethylhexyl) cebacate, was considered. Data on how the structure of flexible and rigid segments affects the physicomechanical properties of the plasticized material, including those at low temperatures, are presented. Ways were determined for obtaining the optimal hybrid structure of the polymers under study for developing materials with enhanced frost resistance.
