Abstract
Viscoelastic behavior and spinnability of acrylonitrile polymer solution in N, N-dimethyl formamide were measured at 50°C.
Dynamic viscosity and dynamic elasticity were measured with a rotational oscillational type viscoelastometer.
The results obtained are as follows:
1) The solution with higher concentration and larger ηsp/C of polymer has larger dynamic viscosity η′ and larger dynamic elasticity G′.
2) The spinnability increases as the polymer concentration and ηsp/C of polymer increase.
