Viscosities of dilute acrylonitrile polymer solution containing various kinds of non-solvent were measured at 30°C and 50°C (in the case of acetone 30°C and 40°C). Intrinsic viscosity [η] and Huggins' constant were calculated and viscosity change with time of concentrated polymer solution were measured.The results obtained are as follows:A) In the case of dilute solution, 1) Nitromethane, acetone, n-hexane and tetrahydrofuran (THF) increase [η] but k′ decreases with increasing amount of them and temperature rises. They behave as poor solvents.2) Dioxane does not change [η] and k′ below 5 volume % benzene behaves as good solvent below 10 volume %, however, it behaves as poor solvent above that content.B) In the case of concentrated solution, Concentrated solution containing n-hexane increases viscosity with time and with the increasing amount. Benzene, THF and dioxane do not cause viscosity increase below a certain amount, however, they increase viscosity with time.
