Abstract
The chemical composition distribution (CCD) of a high-conversion copolymer of styrene and methyl acrylate was determined by cross fractionation and compared with theoretical CCD. Two systems of chloroform–cyclohexane and 2-hydroxyethyl methyl ether–methanol were found to be appropriate for the cross fractionation of the copolymer. It was shown that CCD, determined by cross fractionation, is in fairly good agreement with the value calculated from the classical theory of copolymerization. What is called the gel-effect appears to be negligible in CCD.
