✦ Synopsis

Abstract

Block copolymers of ethylene oxide and ε‐caprolactone were synthesized by microwave‐assisted polymerization of ε‐caprolactone with polyethylene glycol monomethyl ethers as initiator. The samples thus obtained were characterized by two‐dimensional liquid chromatography with liquid chromatography at critical conditions as the first and liquid exclusion adsorption chromatography as the second dimension. A full baseline separation of all oligomers could be achieved in both dimensions.
