Abstract
Temperature sensitive polymers with pendant dimethyl maleinimide side group s were prepared by the copolymerization of N-isopropylacrylamide (NIPAAm) w ith varying amounts of a functional N-substituted acrylamide (2-(dimethyl m aleinimido)-N-ethylacrylamide, DMIAAm). The polymers were characterized by H-1-NMR, IR, DSC and TGA. Their relative reactivity ratios have been determ ined. Aqueous solutions of the copolymers showed lower critical solution te mperature behaviour (LCST). The phase transition temperatures of the aqueou s solutions of these copolymers decreased with increasing comonomer content and disappeared at DMIAAm contents at or above 15.9 mol-%.
