## Abstract A polyurethane consisting of a poly(propylene oxide) soft segment and a diphenylmethane diisocyanateβ€”hydroquinone di‐(b̃‐hydroxyethyl) ether (HQEE) hard block has been characterized over the composition range of 30 to 60 percent hard block. The flexural modulus varied from 60 to 900 MPa
