摘要：

A reversible phase transition, in aqueous solution, of the colloidal poly(N-isopropylacrylamide) microgel system with an excess specific heat capacity maximum at 307.7 K (in the concentration range 0.05-0.5% m/m) is observed using high sensitivity differential scanning calorimetry(HSDSG); the thermodynamic parameters and turbidimetric changes associated with this transition ace reported.
