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 effect of solvent on the reactivity of a polyisocyanate (Desmodur L75) is reported. It is found that this molecule in certain solvent mixtures is less reactive than predicted and the possibility of solvent sheath effects reducing the "effective" reactivity is discussed. The implications of these
