- Using a microscope-television-video camera system, the diffusion coefficients of blend acrylic polymer dopes in the coagulation of a wet spinning process are determined in both dimethylformamide and aqueous NaSCN solvent systems, along with the effects of various dispersing polymers and their composition and content (blend ratio) on the diffusion coefficients. The relationship between the diffusion coefficients and the microporous structure is discussed.
