A series of polycaprolactone/4,4'-diphenylmethane diisocyanate/l,4-butanediol (PCL/MDI/ BDO) segmented polyurethanes of different compositions was synthesized by solution po- lymerization. The molecular weight of PCL diols used was in the range of 1600-7000. The crystallinity and morphology of these

A series of eight thermoplastic polyurethane elastomers were synthesized from 4,4'-methylene diphenyl diisocyanate (MDI) and 1,4-butanediol (BDO) chain extender, with poly(hexamethy1ene oxide) (PHMO) macrodiol soft segments. The soft segment molecular weights employed ranged from 433 g/mol to 1180 g
