Thermoplastic polyurethane elastomers were prepared from 4,4-diphenylmethane diisocyanate (MDI)/1,4-butanediol (BD)/poly(propylene glycol) (PPG) and MDI/BD/poly(oxytetramethylene glycol) (PTMG). The MDI/BD-based hard-segment content of polyurethane prepared in this study was of 39 -65 wt %. These po
Two series of thermoplastic polyurethane elastomers [poly(propylene glycol) (PPG) based PP samples and poly(oxytetramethylene)glycol (PTMG) based PT samples] were synthesized from isophorone diisocyanate (IPDI)/1,4-butanediol (BD)/ PPG and IPDI/BD/PTMG. The IPDI/BD based hard segments contents of po
Neutralization of maleated EPDM rubber by zinc oxide results in an ionic elastomer. The rate and extent of the neutralization reaction increase by addition of stearic acid. Although the rubber is not easy processable as such, incorporation of zinc stearate at a loading of 30 phr makes the rubber beh
