  • Cellulosic-liquid composite materials and process of preparing such materials
    Patent number: 4029726
    Abstract: Polymer-liquid composite materials, particularly of cellulosic polymers such as cellulose nitrate, are described, which materials are strong, transparent, ultramicroporous materials characterized by a diffusion-supporting liquid phase of about 70% or more liquid within an interpenetrating, form-retentive, solid polymer phase. The materials are prepared by precipitation from a hydrogen-bonding solvent solution by the use of a miscible nonsolvent at temperatures generally below about 45.degree. C.
