Abstract
Flame - resistant acrylonitrile copolymers, which are highly receptive to acid dyestuffs, comprise (a) 5-15% by weight of vinylidene chloride units, (b) 1-5% by weight of units of an amino-ester of the formula (where R1 is H or methyl, R2 and R3 each is methyl or ethyl, and n is 2, 3 or 4) and (c) as the balance, acrylonitrile units. In a modification, 1-15% by weight of the acrylonitrile units (based on total copolymer units) are replaced by units of at least one neutral monomer (other than vinylidene chloride) copolymerizable with acrylonitrile. The optional neutral monomer component may be an alkyl, aryl or aralkyl (meth)acrylate, styrene, a-methylstyrene or other substituted styrene, a vinyl ester, e.g. acetate or formate, an unsaturated aldehyde or ketone, an alkacrylonitrile, or (meth)acrylamide or an N-substituted derivative thereof. The copolymers are prepared by polymerizing the corresponding monomers in the presence of a free radical-liberating catalyst or radiation, e.g. azobisisobutyronitrile, benzoyl peroxide, potassium persulphate, sodium chlorate/sodium sulphite or light radiation. Polymerization may be effected in bulk, emulsion, solution or suspension and can be performed batchwise or continuously. The copolymers can be dissolved in solvents such as dimethylformamide or y-butyrolactone to form spinning solutions. When the copolymer contains a relatively large proportion of vinylidene chloride units, the copolymer is suitably dissolved in an aqueous solution of an alkali metal, alkaline earth metal or ammonium thiocyanate having a concentration satisfying one of the following relationships:- (a) 5À3 # x # 7À4 and 47 # y #60 or (b) 7À4 # x # 12À0 and 0À8x + 41À1 # y # 60 where x is the content (per cent by weight) of vinylidene chloride units in the copolymer and y is the concentration (per cent by weight) of the thiocyanate in the aqueous thiocyanate solution. There may also be incorporated into the copolymers, during the course of polymerization or in the preparation of the spinning solutions, a conventional flame-resisting agent such as antimony trioxide or tricresyl phosphate.
