| Abstract: | This work deals with the determination of the various azeotropies in radical terpolymerization: unitary azeotropy (mi = Mi); binary azeotropy (mi/mj. = Mi/Mj), and ternary or true azeotropy (Mj = mj for j = 1, 2, 3). General analytical solutions are given which are easily handled by a computer. In addition, these calculations show the existence of pseudo-azeotropy where the deviation between polymer and monomer feed compositions is very small, not only at the beginning of the reaction, but also with increasing conversion. |
