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.
Two elastomers having reactive functional groups may react with each other. Considering this, the blends of PU and EPH elastomers have been prepared where better performance properties can be tailored and optimized through the interchain crosslinking reaction. It is evident from the IR spectral anal
