Abstract

1293491 Filaments of poly-#-amides FARBWERKE HOECHST AG 28 May 1971 [2 June' 1970] 17859/71 Heading B5B Filaments are made by spinning a formic acid solution of a poly-#-amide into a coagulation bath comprising at least 30% by wt. of an organic solvent miscible with formic acid, the bath containing not more than 1% of inorganic salts. Polymers exemplified are poly-4-methyl- and poly-3,4-dimethyl-acetidin-2-one and a copolymer thereof. Coagulants exemplified are ethanol, cyclohexanone, ethyl formate, DMF, aqueous DMF (59/41), dimethylacetamide and N-methyl pyrrolidone. Other polymers and coagulants are listed. The spun filaments may be stretched in hot or cold water and/or hot stretched on a plate at about 250‹ C. before final drying and windup.
