| titleOfInvention | Production of pulp particle |
| abstract | PURPOSE: To obtain the titled pulp particles having high heat resistance and strength, and useful as a raw material for synthetic paper, etc., by forming molded materials of molecular orientation from an optically anisotropic solution of a wholly aromatic rigid polyamide, applying shear force to the molded materials at the same time, crushing the molded materials into fibers, and fibrillating the fibers. n CONSTITUTION: An aromatic diamine, e.g. p-phenylenediamine, is polymerized with an aromatic dicarboxylic acid derivative, e.g. terephthaloyl chloride, in a solvent in the presence of potassium carbonate, etc. to give a wholly aromatic rigid polyamide constituted of repeating units expressed by formula I (Ar 1 and Ar 2 are bifunctional aromatic groups expressed by formula II, III, IV, or V or a mixture thereof). The resultant wholly aromatic rigid polyamide is then dissolved in sulfuric acid, etc. to prepare an optically anisotropic solution, which is then molded into molded materials having molecular orientation. Shear force is applied to the molded materials by mechanical operation simultaneously with the molding to crush the molded materials into fibers, which are fibrillated to afford the aimed pulp particles. n COPYRIGHT: (C)1985,JPO&Japio |
