Polyester based polyurethanes were synthesized from low molecular weight polyester 2000) and 4,4@-methylene bis(phenyl isocyanate) (MDI) with (M n butanediol as a chain extender and glycerol as a crosslinker. The polyester was synthesized from adipic acid and glycol which was a mixture of 1,6-hexane
Stress-strain and stress-relaxation behavior of polyurethane elastomers based on poly(ethy1ene adipate), poly(ethy1ene maleate), polyethylene glycol, and 4,4'-diphenylmethane diisocyanate (MDI) have been studied. The elastomers were crosslinked by an excess of MDI and by dicumyl peroxide (DiCup); th
