This article examines the effects of the soft-segment composition on the structure and physical properties of waterborne polyurethane (WBPU) based on polycaprolactone-poly(ethylene glycol) -polycaprolactone (PCL-PEG-PCL) triblock copolydiol as the soft segment. The molecular weight of PEG in the sof
## Abstract Two series of poly(ether urethane)s and one series of poly(ester urethane)s were synthesized, containing, respectively, poly(oxytetramethylene) diol (PTMO) of __M__~__n__~ = 1000 and 2000 and poly(ฮตโcaprolactone) diol of __M__~__n__~ = 2000 as soft segments. In each series the same hard
