THIS IS ALL THE INFO GIVEN

THIS IS THE PROBLEM. IM NOT SURE WHAT EQUATIONS CAN HELP BUT MAYBE AN EXAMPLE

Consider situation shown in the figure. You have a mixture of two polymers with equal numbers of a segments (both segments are of the same size) that is in the miscible region of the (UCST) phase diagram You want to change the state of the system from being miscible to becoming immiscible. You cannot change the composition of the mixture, pressure, you are not allowed to add any other chemical moiety to or remove anything from the system. All you can do is to either vary temperature or change molecular weight. How can you accomplish this and why? (Assume that the system behavior is well described by the Flory- T Huggins theory). Use equations if you can to prove your point. You are here Composition

Explanation / Answer

from the phase diagram given if we decrease the temperature we can make the components immissible again. The tempertue range has be within the range of the curve.
