Abstract

Fibres and films are formed by melt extrusion from isotactic polypropylene containing up to 25% of atactic polypropylene and one or more substances stable at temperatures between 180 DEG and 320 DEG C. and selected from the groups consisting of (a) ultra-violet light absorbers, (b) antioxidants, (c) free-radicle inhibitors and (d) metal ion inhibitors. The substances used in the examples are (a) pigments such as 2-hydroxy-4-methoxy-benzophenone, 2,21-dihydroxy-4-methoxy-benzophenone, carbon black, 2-mercapto-benzimidazole + 2,21-dihydroxy-3,31 di[1-methylcyclohexyl]-4,41-dimethyl-diphenyl-methane, and paraphenylenediamine; (b) phenolic and amine compounds such as 2,21-dihydroxy-3,31 - di[1 - methylcyclohexyl] - 4,41 - dimethyl - diphenylmethane, 2,21-dimethyl-4,41-dihydroxy-5, 51-ditertiarybutyl-diphenyl sulphide, paraphenylenediamine, and N-lauryl-para-amino-phenol; (c) carbon black; and (d) metal complexing, sequestering and chelating agents such as the mixture of 2-mercaptobenzimidazole with 2,21 -dihydroxy - 3,31-di[1-methyl - cyclohexyl] - 4,41-dimethyl-diphenyl methane. The examples compare the properties of fibres (with and without said additives) which are formed by spinning and then drawing. An application specified is the production of ropes. Specifications 810,023 and 847,235 are referred to.
