Fig. 5. Data from the PITSA chain extension of a N,N-dimethylacrylamide (DMA) and acrylic acid (AA) containing macro chain transfer agent, [polyDMA34-b-poly(DMA14-co-AA6)], with N-isopropylacrylamide (NIPAm) at 70 °C. (a) First-order kinetics plot showing an increase in rate during the polymerization. Inset: M n vs. conversion. (b) SEC traces showing unimodal distributions shifting to higher molecular weights as the polymerization proceeds.
