1,126,203. Polyolefin compositions. EASTMAN KODAK CO. 20 Oct., 1965 [21 Oct., 1964], No. 44402/65. Heading C3P. Compositions comprise a crystallizable polyolefin having dispersed therein a metal-free crystallization promoter which is compatible with the polyolefin and exhibits a liquid crystalline state at a temperature below the melting- point of the polyolefin, said promoter being (a) a mono- or di-N-substituted ammonium salt of an aromatic sulphonic acid, (b) an N-substituted ammonium salt of an aromatic or aliphatic carboxylic acid or (c) an amide complex of an aromatic carboxylic acid. Specified polyolefins are polyethylene, polypropylene, polybutene -1, poly - 4 - methyl pentene - 1, and ethylene/propylene, propylene/butene-1, propylene/hexene-1 and propylene/decene-1 copolymers. Specified promoters are amine salts of alkylbenzoic acids, N-substituted ammonium aromatic sulphonates, N-substituted ammonium salts of aromatic and aliphatic carboxylic acids and complexes of phosphoric acid amides and carboxylic acid amides with carboxylic acids, many suitable promoters being listed. The compositions may be made into filaments and non- blocking sheets and films of good transparency. Examples describe compositions comprising (1) polypropylene and dibutylammonium p-t-butyl benzoate, dibutylammonium 1-naphthoate or methylphenylammonium p-toluate; (2) polyethylene and piperidinium p-t-butylbenzoate, piperidinium p-isopropylbenzoate or dihexylammonium 1-naphthoate; (3) polyethylene and diamylammonium o-toluate, tributylammonium p-t-butylbenzoate or dimethylammonium p-toctyl benzoate; (4) polybutene-1 and piperidinium p-isobutylbenzoate, piperidinium p-tbutylbenzoate or cyclohexylammonium mtoluate; (5) a propylene/butene-1 stereoblock copolymer and dibutylammonium p-toluate, piperidinium benzoate or dibutylammonium anthracene-1-carboxylate; (6) propylene/butene-1, -hexene-1 or -decene-1 copolymers and isobutylammonium p-isopropylbenzoate, octylammonium 2-naphthoate or t-butylammonium p-t-butylbenzoate; (7) poly-4-methylpentene-1 and methylbenzylammonium p-ethylbenzoate, didecylammonium p-phenylbenzoate or diethylammonium p-dodecylbenzoate; (8) an ethylene/ propylene block copolymer and dibutyl-ammonium p-t-butylbenzoate; (9) polypropylene and dibutylammoniumbenz ene sulphonate, dibutylammonium 2 - naphthalenesulphonate or methylphenylammonium benzenesulphonate; (10) polyethylene and dibutylammonium p-tbutylbenzene sulphonate, piperidinium benzenesulphonate or dihexylammonium 1-naphthalene-sulphonate; (15) polypropylene and dibutylammonium succinate, dibutylammonium sebacate or methylphenylammonium glutaconate; (16) polyethylene and piperidinium glutarate, piperdinium pimelate or dihexylammonium α,α-dimethylsuccinate; (23) polypropylene and hexamethylphosphoric acid triamide / p-t-butyl benzoic acid, tripiperidinophosphine oxide / p-isopropyl benzoic acid or hexabutylphosphoric acid triamide/p-toluic acid complexes; (24) polyethylene and hexabutylphosphorous acid triamide/p-isopropylbenzoic acid, N,N dimethylacetamide/p - n - butyl - benzoic acid or N,N-dimethylformamide/ p - t - butyl benzoic acid complexes; and (30) an ethylene/propylene block copolymer and hexamethylphosphoric triamide/p-t-butyl benzoic acid, N,N,N1,N1 - tetramethylphenylphosphonic diamide/p-t-butylbenzoic acid or N,N - dibutyldiphenylphosphinic amide/p - iso - propylbenzoic acid complexes.
