发明名称 PARA-ARAMID FIBRID FILM
摘要 <p>The invention relates to a para-aramid fibrid film, characterized in that at least 95% of the bonds of the polymer are para-oriented, and to 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 by using conventional methods known for making meta-aramid fibrid.</p>
