Cationic copolymerization of tetrahydrofuran with epoxides. II. Characterization and gel‐permeation chromatography of by‐products formed during polymerization

Abstract

Abstract The cyclic oligomers formed as by‐products in the polymerization of propylene oxide. 1,2‐butylene oxide, and n ‐propyl glycidyl ether, and in the copolymerization of these monomers with tetrahydrofuran have been studied by gel‐permeation chromatography and otherwise and their structures have been determined. Some of the physical properties of the cyclic oligomers are described.
