    We have synthesized and characterized a thermoresponsive micellar radionuclide delivery systems based on ABA triblock copolymers poly[2-methyl-2-oxazoline - block - (2-isopropyl-2-oxazoline - co - 2-butyl-2-oxazoline) - block - 2-methyl-2-oxazoline]. These polymers are molecularly dissolved in aqueous millieu below cloud point temperature (CPT) of the thermoresponsive central block and above its CPT they form polymer micelles with diameter ~ 200 nm. A phenolic moiety introduced into the copolymer allowed radionuclide labeling with 125I ongoing in good yield with sufficient in vitro stability under model conditions.
