| has gloss | eng: The lower critical solution temperature (LCST) is the critical temperature below which a mixture is miscible in all proportions. In the phase diagram of the mixture components, it is the shared minimum of the concave up spinodal and binodal curves. The LCST is in general pressure dependent, with increased pressure generally increasing the LCST. In the case of polymer mixtures, it also depends on polymer degree of polymerization, polydispersity and branching . A prominent polymer possessing an LCST is Poly(N-isopropylacrylamide), which undergoes a reversible collapse transition related to the LCST at 33°C. |
