Abstract Copolymerization of phenyl isocyanate with ethylene oxide was investigated under several conditions. The polymers obtained with AlEt 3 alone or the AlEt 3 ‐H 2 O system as catalyst were found to be composed of two types, that is polyethylene oxide and alternate copolymer of phenyl isocyanate with ethylene oxide. The copolymer was found to have acetalic units in the polymer chain.
