PROCEDE D'OBTENTION D'UNE FIBRE ACRYLIQUE BICONSTITUANTE

The process comprises coagulation based on binary copolymers (90.5:9.5 acrylonitrile:methyl methacrylate, and polyethylene glycol acrylonitrile acrylate). The bath contains 20 per cent of ethylene carbonate in water at 50-60 degrees C. The filaments are drawn at 1:4.7 and 1:1.3 in the gel and the dr...

Zusammenfassung:	The process comprises coagulation based on binary copolymers (90.5:9.5 acrylonitrile:methyl methacrylate, and polyethylene glycol acrylonitrile acrylate). The bath contains 20 per cent of ethylene carbonate in water at 50-60 degrees C. The filaments are drawn at 1:4.7 and 1:1.3 in the gel and the dry state respectively, with increase in productivity and product range.
