I am learning something about polymer solution which has LCST phenomenon. But I met researchers used demixing temperature and cloud point to describe the transformation of this kind of solution from solutable into insolutable state. But for me, they seem the same. So I ask it here to learn what is the difference between these two concepts?

Cloud point typically refers to the LCST (or UCST) in solution. Demixing temperature usually refers to the LCST (or UCST) of a polymer mixture or copolymer in bulk.
