Poly(esterurethane) elastomers were synthesized by a pre-polymer process. The pre-polymer based on poly(caprolactone) (capa-225) and toluenediisocyanate (TDI) was mixed with 1,4-butane diol (BDO) or dihydroquinone (HQ) in capa-225 (known as the quasi pre-polymer process) and then reacted in a mould.
The effects of five different types of fillers on the thermal and mechanical properties of hydroxyl-terminated polybutadiene-based polyurethane elastomers were explored to develop a filled polyurethane elastomeric liner for rocket motors with hydroxyl-terminated polybutadiene-based composite propell
