Abstract
A resilient polyurethane elastomer structural member is made from (A) a prepolymer prepared from a composition consisting essentially of 2.60 moles to 2.80 moles of 4,4'-diphenylmethane diisocyanate, and about 0.23 mole to about 0.31 mole of a low molecular weight triol, per 1.0 mole of polyoxytetramethylene glycol, and (B) hydroquinone di-(.beta.-hydroxyethyl) ether, as a chain extender. This polyurethane elastomer can be used to make annular missile shock isolator pads useful for the land based, MX (Peacekeeper) missile.
