Butadiene-oxyethylene multiblock copolymers were synthesized via coupling reaction of telechelic a,x-dihydroxypolybutadiene (PB) and poly(ethylene glycol) with tolylene-2,4-diisocyanate. The poly(oxyethylene) (PEO) content of the purified copolymer was determined by elemental analysis and the struct
