Hard Segment Inelastic Effects on the Stress-Strain Response of Polyurethane Elastomers Based on Hard Segments of Variable Geometry

Abstract:

A study was made of a family of thermoplastic polyurethane copolymers, in which the nature and number of the hard segment components (crystallizing or not) were varied. Materials were synthesized with ethylene glycol (EG) as chain extender. Changes induced by varying the type and the number of isocyanates and the order of their introduction were followed and the mechanical responses were measured in cyclic tensile tests and stress relaxation in interrupted tests. Polymers based on DBDI hard s...
