Thermosensitivity studies of hyperbranched dendrimers and branched polymer with terminal N-isopropylamide

A series of N-isopropylamide terminated poly(amidoamine) dendrimers and the stoichiometric conjugation between a dendrimer and long chain polyethylene glycol (10 KD) were synthesized and their thermoresponsive properties were studied. The relationship between surface functionality and thermoresponsive properties of both modified dendrimers and branched polymers was investigated, demonstrating molecular design principles for thermoresponsive properties in novel polymeric materials.
