Abstract
Linear polyurethane was prepared from a well-defined poly (oxytetramethylene) glycol (PTMG), with oligomers having a various molecular weight distribution (MWD), and a reacted 4, 4′-diphenylmethane diisocyanate (MDI). These linear polyurethanes were crosslinked with a peroxide to produce polyurethane elastomers. The effect of average number of repeating unit (n) and MWD of PTMG on crystallization behavior for polyurethane elastomer was studied by DSC, WAXD, and stress relaxation. The crystallinity of the polyurethane elastomers was reduced not only by decreasing n but also by narrowing MWD of the PTMG. The polyurethane elastomer designed here, showed good strain-induced crystallization behavior and less stress decay.
