Title:
パラ-アラミドと添加剤物質とのコンポジットを含有する粒子
Document Type and Number:
Japanese Patent JP5224614
Kind Code:
B2
Abstract:
The invention pertains to a method for making a polymer-additive composite particle from a dope by jet spinning the dope to obtain a pulp, fibril or fibrid, wherein the solvent of the dope is selected from N-methyl-2-pyrrolidone, N,N′-dimethylformamide, N,N′-dimethylacetamide, tetramethylurea, and 4 to 75 wt % of a composition consisting of 2 to 95 wt % of a para-aramid polymer and 5-98 wt % of a solid additive material, to a total of 100 wt %, and wherein the aramid polymer is dissolved in the solvent; or coagulating the dope by means of a rotor-stator apparatus in which the polymer solution is applied through the stator on the rotor so that the precipitating polymer-additive composite particle is subjected to shear forces while they are in a plastic deformable stage.
