Definitions

  • This invention relates. to a process for producing a spinning solution from polyacrylonitrile or copolymers thereof.
  • Example 1 200 g of polyacrylonitrile having a K-value of were stirred in 800 g of a solvent mixture consisting of 80 percent by Weight of glycolic acid nitrile and 20 percent by weight of methylene glycol diacetate, at a temperature of about 15 C., to form a suspension. While the suspension was stirred, it was deaerated in a vacuum. After about one hour the deaerated mixture was heated gradually to a temperature ranging between and C. and stirring was continued for another hour at this temperature.
  • the spinning solution thus obtained was found to be satisfactory in every way and was then spun continuously according to the dry-spinning method.
  • the threads or filaments were stretched in hot condition in two steps, to from 8 to 10 times their original length. These threads or filaments were found to present a particularly uniform cross-section and to display a favorable strength of about 40 breaking km. at an elongation of between 7 and 8 percent.
  • Example 2 200 g of a copolymer consisting of 90 percent by weight of acrylonitrile and 10 percent of acrylic acid amide were stirred in cold condition together with 800 g of a solvent mixture containing 75 percent by weight of glycolic acid nitrile and 25 percent by weight of methylene glycol dibutyrate, to form a suspension which was then Worked up, in accordance with Example 1. On being spun the solution thus obtained proved very satisfactory and the threads or filaments produced from it had a particularly favorable strength of about 45 breaking km. at an elongation of about 8 percent.
  • n may be a numeral between 0 and 2.
