Abstract
The abnormal behavior of acrylonitrile polymers shown by size exclusio n chromatography (SEC) in N,N-dimethylformamide (DMF) was investigated by using model polymers having variable degrees of sulfonated moietie s as electric charged groups. The unexpected small retention volume an d very high UV absorption at 280 nm were observed in the case of the s amples with ionic sulfonate groups even in very small amounts, as chai n ends. The abnormal behavior was confirmed to be due to impurities of DMF decomposition which interact with charged groups in the polymers.
