A P(NIPAAm-co-DOT) copolymer was also synthesised along with a PNIPAAm homopolymer as a reference (Table , samples 8 and 9, respectively). Similar to AAm, DOT copolymerised with NIPAAm, with both monomers achieving high conversions after 20 h. Again, there was good agreement between f DOT (0.05) and F DOT (0.06) for sample 9 and good correlation between the targeted DP n and the observed M n , despite a slightly higher Ð. Interestingly, all the P(AAm-co-DOT) copolymers synthesised were fully water-soluble in ambient conditions despite the addition of the hydrophobic DOT moiety. However, the P(NIPAAm-co-DOT) copolymer (sample 9) was insoluble in water at all temperatures. This is likely a result of the increased hydrophobicity of PNIPAAm compared to PAAm.
