Figure 9.

Phase diagram of a mixture of trifunctional A molecules and bifunctional B molecules in a solvent, whose functional groups are completely miscible in a range of multiplicity between 3 and 5. Solution of A molecules has SGT without B molecules, whose gel concentration monotonically decreases by mixing B molecules. Spinodal line for an interaction parameter ${\chi }_{A,B}=5.0$ between A- and B molecules in a good solvent (green broken line) and in a solvent poor to A molecules ${\chi }_{A,0}=0.9$ (blue broken line) are also drawn. For the latter, there is a critical B concentration above which the solution becomes uniform.
