    Abstract: 1466601 Paper BASF AG 17 Oct 1974 [18 Oct 1973] 44967/74 Heading D2B [Also in Division C3] Paper-like products may be prepared from aqueous suspensions of polyolefin fibrids prepared in the presence of a dispersing agent which comprises 0.1 to 2 per cent by weight of the fibrids of an anionic protective colloid. The suspensions may also contain cellulose fibres. Examples describe the preparation of paper-like products from aqueous suspensions of equal weights of sulphite cellulose fibres and polyethylene fibrids prepared using urea/formaldehyde/sodium phenol sulphonate polycondensate, urea/formaldehyde polycondensate modified with sodium bisulphite, sodium salt of carboxymethyl cellulose, ammonium salt of maleic acid/vinyl isobutyl ether copolymer or ammonium salt of acrylic acid/styrene copolyer; and from 70/30 50/50 and 30/70 mixtures using the above protective colloids or formaldehyde/sodium #-naphthalene sulphonate condensate.

    Abstract: 1386809 Phosphorus impregnated with trioxane BADISCHE ANILIN- & SODAFABRIK AG 8 June 1972 [9 June 1971] 26696/72 Heading C1A [Also in Division C3] The invention comprises red phosphorus impregnated with trioxane preferably in an amount of 20-80% based on the wt. of the mixture. The trioxane may be stabilized with 10-200 p.p.m. of triethylamine or triethanolamine and 50-150 p.p.m. of 2,6-di-tert-butyl-p-cresol as an antioxidant. The impregnated phosphorus can be incorporated into thermoplastics (see Division C3) to render them self-extinguishing or flame resistant.

    Abstract: 1,234,057. Stabilizing oxymethylene polymers by addition of a #-aminolactamide. BADISCHE ANILIN- & SODA-FABRIK A.G. ]6 Oct., 1968 [17 Oct., 1967 (2)], No. 48967/68. Heading C3P. Compositions comprise an oxymethylene polymer and a stabilizing compound of formula where R 1 is H, OH, NR 2 R 2 , -CH 2 -CH(OH)- CONH 2 , in which m is 1 to 3 and n is 1 or 2, or m is 1 and n is 1 to 3, or in which m + n is 1 to 5 and m is 1 to 5, and R 2 is H or CH 2 .CH(OH)-CONH 2 . Phenolic antioxidants and a polycondensate of isophthalic diamide, a cyclic -N,N 1 - alkylene urea having 2 to 5 carbon atoms, and formaldehyde may also be included. In the examples, trioxan-1,3- dioxolan copolymers treated with NaF are stabilized with nitrilotrilactamide or ethylene diamine tetralactamide and a conventional bisphenol.
