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
Abstraet--A series of nine polyurethanes with a systematically varying hard to soft segment ratio was prepared; their dynamic mechanical spectra were studied over a wide temperature range. These polyurethanes were prepared using Adiprene L-100 which contains polyether units (forming the soft segment
