- 摘要： The coagulation phase separation of solutions of novel copoly(phthalazinone amide)s is studied by the cloudpoint titration method. The effects of some factors on the coagulation value (V-1) and critical concentration (C-c) are investigated. It is shown that water is a strong coagulant, having a low coagulation value V-1 and that the V-1 increases with the increase of coagulant concentration and temperature. In addition, an increased percentage of LiCl in the coagulant and of phthalazinone moiety in the polymer main chain can slow down the phase separation speed.
