초록

This thermoplastic elastomer is present in a substantially solid state suitable for use as a binder for a propellant, explosive, and/or gas generant of a supplemental restraint system. The thermoplastic elastomer is formed from a composition including A blocks which are crystalline at temperatures below about 75째 C. and B blocks which are...

대표
청구항

What is claimed is: 1. An energetic thermoplastic elastomer, comprising: A blocks terminated with isocyanate-reactive groups derived from monomers comprising at least one oxetane derivative, the A blocks being crystalline below about 60째 C.; B blocks terminated with isocyanate-reactive groups derived from monomers comprising at least one member selected from the group consisting of oxirane and derivatives thereof, the B blocks being amorphous above about-20째 C.; and linking groups derived from at least one diisocyanate and at least one linking compound ...
