摘要：

Blend films of cellulose with poly(vinyl alcohol), polyacrylonitrile, poly(epsilon-caprolactone), and nylon 6 were prepared from mixed solutions in N,N-dimethylacetamide-lithium chloride by coagulation in a nonsolvent. From solid-state NMR relaxation measurements the scale of miscibility of the different blends was evaluated. The values lie in the range from 4 to more than 30 nm. The possible factors affecting the results are discussed.
