- Abstract
A polyurethane elastomer was synthesized using oligoethylene adipate, 2,4-diisocyanato-1-methylbenzene, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, and 2,2′-[propane-2,2-diylbis(p-phenyleneoxy)]diethanol as a chain extender was synthesized. It was discovered that the resulting polyurethane is amorphous and demonstrates superior properties compared to crystallized counterparts made with 1,4-butanediol or 4,4′-(propane-2,2-diyl)diphenol as a chain extender. These superior properties include hardness, breaking elongation, elasticity, and thermal stability.
