Lower critical solution temperature versus volume phase transition temperature in thermoresponsive drug delivery systems

eXPRESS Polymer Letters, 2011
One of the most subtle problem in the characterization of thermoresponsive polymers is the evaluation of the relationship between the lower critical solution temperature (LCST) of the linear polymer and the volume phase transition temperature (VPTT) of ...
