摘要：the production of the above fibers is such that it (a) 20 to 80 'c a solution ofactivated cellulose in dimethylacetamide or 1 - methyl - 2 - pyrrolidon produces, 5 to30%.-% activated cellulose of a durchschnittspolymerisationsgrades from 300 to 800 and3 to 20% by weight.-% licl contains, (b) those with the corresponding

dicarbons\äureanhydriden in a mole ratio of 1 led to: 0.20 to 1: 4 to 20 to 120 in thepresence of known veresterungskatalysatoren up to a degree of esterification of 0.1 to1.7 implements(c) the cellulosemonoesterl\ösungen in a koagulationsmittelna\ßverspinnt and) the fibers from the cellulosemonoestern of phthalic acid and, ifnecessary, from the cellulosemonoestern of maleic acidand succinic acid in a substantiallyorganic solvent through the implementation with alkalimetallhydroxyden and or

alkalimetallalkoholaten or ammonia or primary or secondary amines teilweise or entirelyin faserf\örmige salts convicted.
