Correlations between chemical structure, stress‐induced crystallization, and deformation behavior of polyurethane elastomers

摘要

AbstractThe deformation behavior of polyurethane elastomers depends strongly on physical interactions.In this paper the stress‐induced crystallization of the polyester or polyether segments in investigated in several polyurethane elastomer systems having different chemical structure for the soft segments. The correlation between the tensile properties (hysteresis loss, extension set, modulus) and the stress‐induced crystallization is discus
