Abstract
1436174 Polyacrylonitrile monofilaments CESKOSLOVENSKA AKADEMIE Ved 5 July 1973 [14 July 1972] 32142/73 Heading B5B [Also in Divisions B8 and C3] A polyacrylonitrile monofilament comprises a partially hydrolysed monofilament of a block copolymer polyacrylonitrile having a water content at swelling equilibrium of between 30 and 60% by wt. and an elastic elongated, when oriented of between 10 and 50% of its rest length. Preferably acrylonitrile is polymerized in concentrated nitric acid at 10- 40‹ C. and the subsequent partial hydrolysis effected at -10‹ to +50‹ C. over a period of days, the polymer solution then being spun through air into a coagulation liquid, e.g. water, diluted HNO 3 or a mixture of water and a C 1 to C 4 aliphatic alcohol or glycol, followed by washing and stretching to orient the fibre.
