Abstract
The invention relates to a homogeneous fluid composition which can be shaped, consisting of N-methylpyrrolidone-2, poly-para-phenyleneterephthalamide in an amount of 5 to 7% by weight, relative to the weight of the composition, calcium chloride or lithium chloride, and a tertiary amine with a pK H.sub.2 O equal to at most 6.60, and also to the process for its production. The composition can be shaped directly to form filaments, fibres, films or fibrids which can be used, for example, in the textile industry.
