Abstract
The effect that the molecular weight of oligoethylene adipate exerts on the properties of urethane-containing elastomers is studied. Three oligoethylene adipates have been obtained by means of adipic acid and ethylene glycol polycondensation. Based on these polyesters, as well as isophorone diisocyanate and aromatic diamine 3,3'-dichloro-4,4'-diaminodiphenylmethane, three polyurethane ureas are obtained. The deformation and strength properties of these elastomers have been studied.
