## Abstract The formalized kinetic approach to the mechanism of urethane formation in the system of prepolymer with end NCO groupsβ1,4βbutanediol together with the dispersion analysis of kinetic curves have helped to establish that, at moderate temperatures, the mechanism may be represented by a sc
Thermoplastic polyurethane elastomers (TPUs) of constant composition were prepared by using the prepolymer method and by changing the reaction conditions (prepolymerization and chain-extension time) to study the influence of these conditions on the final TPU properties. The TPUs were characterized b
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.
