| titleOfInvention | Process for stabilising polyacrylonitrile |
| abstract | Acrylonitrile homo-polymers and co-polymers containing at least 80% of polymerized acrylonitrile are stabilized against discolouration by the incorporation of an effective amount of a five-membered or six-membered heterocyclic compound containing a <FORM:0956095/C3/1> grouping or tautomer thereof in the heterocyclic ring. Preferably 0.01-5% by weight of the stabilizer is added to the polymer. Any desired solvents may be used in shaping the acrylonitrile polymer, for example dimethyl formamide or dimethyl acetamide. The stabilizer can be a mercaptoderivative of imidazole, dihydroimidazole, benzimidazole, pyrimidine, dihydropyrimidine, 1,2,4-imazole, dihydro 1,2,4-imazole, 1,2,4-triazine or tetrahydrazine or an alkyl or amino substitution product thereof. The copolymers of acrylonitrile contain one or more co-monomers, such as vinyl acetate, styrene, vinyl chloride, acrylic and methacrylic esters and amides, unsaturated carboxylic acids (such as acrylic and methacrylic acids). Unsaturated sulphuric acids (such as vinyl-sulphonic and styrene-sulphenic acids) or unsaturated bases (such as vinyl pyridine and alkyl-vinyl pyridine. The use of copolymers of acrylonitrile and methyl acrylate, and methyl acrylate and 2-methyl-5-vinyl pyridine is exemplified. |
