摘要： A para-aramid fibrid film is disclosed that has at least 95% of the bonds of the polymer are para-oriented. A method for making said para-aramid fibrid film by (a) polymerizing a para-oriented aromatic diamine and a para-oriented aromatic dicarboxylic acid halide to an aramid polymer having only para-oriented bonds in a mixture of solvents consisting of N-methylpyrrolidone or dimethylacetamide and calcium chloride or lithium chloride to obtain a dope wherein the polymer is dissolved in the mixture of solvents and the polymer concentration is 2 to 6 wt. %, and (b) converting the dope to para-aramid fibrid film is also described.

摘要： The invention relates to a non-fibrous polymer solution essentially consisting of 1 to 8 wt. % para-aramid, at least 50 mole % of the aromatic moieties thereof being unsubstituted, in a mixture of a) a polar amide solvent selected from N-methyl-2-pyrrolidone, N,N′-dimethyl-formamide, N,N′-dimethylacetamide, tetramethylurea, and mixtures thereof; b) between 0.7 mole of an alkali or alkaline earth metal chloride per mole amide groups of the para-aramid and 7.5 wt. % of the alkali or alkaline earth metal chloride, and c) water; and wherein at least 50 wt. % of the formed hydrochloric acid has been neutralized to obtain a solution having a dynamic viscosity which is at least a factor three smaller than the dynamic viscosity of the polymer solution without neutralization. The invention further pertains to a process making the same and para-aramid pulp-like fiber, paper and film made from said polymer solution.
