Notes:
The miscibility of copolymers AxB1-x and AyB1-y, derived from the same monomer pair (A, B) but differing in composition, was studied. The systems (A, B) were (S, MMA), (BMA, MMA), (S, BMA), and (CIS, BMA) (S: styrene, CIS: p-chlorostyrene, MMA: methylmethacrylate, BMA: n-butylmethacrylate). Miscibility diagrams were recorded, at low and high temperatures, using cast films and dry films. All blend systems feature hightemperature miscibility gaps. Unusual effects of the compositions x and y on miscibility in blends AxB1-x/AyB1-y were observed. The classical prediction that miscibility should depend only on the composition difference |x - y| usually is too simple. It appears necessary to consider dyad interactions.
