For the polymer blend system made of A and B, which contains 30% of polymer A by volume. It is known that the Flory-Huggins interaction parameter () is estimated to be 0.15 , please calculate kSmix,kTUmix, and kTGmix for the polymer blend. It is known that the degrees of polymerization of A and B are 10 and 20 , respectively. (18%) Bonus: calculate the at binodal condition (b) for the system. Will it phase separate? Please give a reason. (10\%) For the polymer blend system made of A and B, which contains 30% of polymer A by volume.
