acomplex coacervate, and a phase depleted of polymer. A hypothetical
phase diagram is in Figure 6.19b. Also forB 23 &0, complex coacervation
will generally occur at high polymer concentration.
Incompatibility. For two polymers that do not have side groups
causing mutual attraction, incompatibility mostly occurs, and the
concentration needed for phase separation is smaller as the molar mass of
the polymers is higher. A good example is the phase separation occurring

glycosidic polymers from those. Thea-form produces amylose, theb-form cellulose.
