A range of P(AAm-co-DOT) copolymers were synthesised with various copolymer compositions and molar masses (Table , samples 1-7). In general, high conversions of both monomers were achieved after 20 h. However, lower conversions were observed after 24 h for AAm and DOT (9 % and 2 %, respectively) with higher f DOT values (0.14, sample 5). Fractionally higher conversions were achieved (13 % and 65 % for AAm and DOT, respectively) when a second dose of initiator was added to the copolymerisation and left for a further 24 h. This demonstrates that high quantities of DOT leads to the retardation of the copolymerisation. This retardation has been previously reported for other copolymer systems. Reasonable correlation between f DOT and F DOT was observed for the series. In general, slightly higher F DOT values were obtained due to the higher conversion of DOT compared with AAm. SEC analysis of the copolymers showed a good correlation between the targeted DP n and the number average molar mass (M n ) with reasonably low dispersities being achieved in all cases. This demonstrates that DOT can be successfully copolymerised with AAm in a range of molar masses and compositions.
