摘要：
The intrinsic viscosity of dilute poly(acrylonitrile-ammonium itaconate) copolymer solution in dimethyl sulfoxide was studied by viscometry. Abnormal phenomena of the eta(sp)/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.
