High molecular weight polycaprolactone prepolymers used in high-energy
formulations
摘要:
Poly(caprolactone) polymers are provided having molecular weights of 4000 or higher, are used to form propellant binders. When the high molecular weight poly(caprolactone) polymers are used in propellant formulations and cured with isocyanates of adequate functionality, propellants are produced having improved stress and strain characteristics relative to presently formulated propellants having binders of cured, lower molecular weight poly(caprolactone) polymers.
