A thermosensitive carrageenan-based polymer: synthesis, characterization and interactions with a cationic surfactant.

Novel polyelectrolytes were obtained by grafting N-isopropylacrylamide (NIPAM) on the ι-carrageenan (CAR) chain. Two polymers with different grafting degrees were synthesized. The polymers were found to show the lower critical solution temperature (LCST) close to that of PNIPAM.
