Glycidyl azide polyol-based thermoplastic polyurethane elastomer and preparation method thereof

摘要

The present invention relates to a glycidyl azide thermoplastic polyurethane elastomer. According to the present invention, a thermoplastic polyurethane elastomer in which polymethyl methacrylate (PMMA) is introduced into a glycidyazide polymer is heated at 50 to 120 ° C It has melt processing temperature and excellent thermal and thermal properties. The thermoplastic polyurethane elastomer of the present invention can be used for a binder for a propellant because it retains high energy content while having excellent mechanical properties.
