Abstract
Using a microscope-television-video camera system, the diffusion coeff icients of blend acrylic polymer dopes in the coagulation of a wet spi nning process are determined in both dimethylformamide and aqueous NaS CN solvent systems, along with the effects of various dispersing polym ers and their composition and content (blend ratio) on the diffusion c oefficients. The relationship between the diffusion coefficients and t he microporous structure is discussed.
