The dilute solution behaviour of poly(monoethyl itaconate) (PMEI) has been studied in 2-ethoxyethanol, methanol, dimethylsulfoxide and water, at 298 K, by intrinsic viscosity and fight scattering measurements, and size exclusion chromatography (SEC). Weight-average molecular weight was determined in
## Abstract The intrinsic viscosities [η] and viscosity constants of high molar mass poly(acrylonitrile‐__co__‐itaconic acid) copolymer in DMF were obtained by the methods of Huggin, Fuoss, Martin and Schulz‐Blaschke. The values of [η] by averaging procedures suggested by Sakai were close to those
## Abstract The viscosity behavior of dimethyl sulfoxide (DMSO) solutions of acrylonitrile–ammonium itaconate copolymer is discussed. The intrinsic viscosity was determined by an Ubbelohde viscometer. It is shown that an increase in the viscosity of acrylonitrile–ammonium itaconate copolymer soluti
