Özet

Aqueous polymerization of acrylamide (AAm) was carried out with the Ce(IV)-dicarboxylic acid initiator system. Dicarboxylic acids with Ce(IV)-dicarboxylic acid initiator system. Dicarboxylic acids with numbers of methylene groups ranging from 1 to 7 were used to elucidate the effect of chain length between the carboxyl groups on the formation of polymer, which is reflected in yield and molecular weight of polymer. The end group analysis of polyacrylamides was carried out by using conductometric titration. The number average molecular weight results from end group analysis are compared with values from viscometric analysis.
