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 synthesis of thermoplastic polyurethane elastomers (TPUs) is generally carried out using the prepolymer method. To study the influence that the properties of the prepolymer may have in the final TPUs, four TPUs were prepared by using different NCO/OH ratios. The prepolymers and the macroglycol u
