PROCESS FOR PRODUCING COMPOSITE FROM SOLUTION OF RIGID POLYMER AND COMPOSITE FILM |
摘要 |
A method of preparing a precursor for a composite having wet strength of 2 to 50 kgf/mm<2> and a mean surface void diameter of 0.01 to 2 mu m by molding a solution of a rigid polymer having a concentration of 1 to 1.3 times the optical anisotropy lower limit solution concentration C2, thereafter rendering the solution non-flowable by absorbing a coagulant under a condition causing no solvent extraction and thereafter extracting the solvent, and a method of preparing a molecular composite having a mean thickness of 2 to 200 mu m by impregnating this precursor for a composite with a solution of a polymer or reactive molecules. |
