Novel poly(oxyethylene)/poly(caprolactone) POE/PCL copolymers were synthesized by step growth polymerization of poly(e-caprolactone) diols and poly(ethylene glycol) diacids using dicyclohexylcarbodiimide as coupling agent. The reaction was performed at room temperature and yielded multiblock copolym

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
Polyurethane iniferter prepared from isocyanate end capped prepolymer and 1,1,2,2-tetraphenyl-1,2-ethanediol, has been used to polymerize vinylbenzyl chloride to obtain polyurethane-polyvinylbenzyl chloride multiblock copolymers. Formation of the block copolymers proceeds with increase in both molec
This study utilizes different types of bisphenol monomers instead of bisphenol-A to synthesize phenol terminated polydimethylsiloxane-polycarbonate block copolymers. The copolymers were synthesized by interfacial phosgenation of β£, -phenol-organofunctional polydimethylsiloxane oligomer with various
