Abstract
The intrinsic viscosity of dilute poly(acrylonitrile–ammonium itaconate) copolymer solution in dimethyl sulfoxide was studied by viscometry. Abnormal phenomena of the ηsp/c versus c curves of poly(acrylonitrile–ammonium itaconate) were found. Owing to the effect of NH4 +, there were three anomalistic turning points in the curve of the Huggins dependence compared with other polyacrylonitrile copolymers.
