Abstract: A process for the manufacture of nonfoaming aqueous suspensions of polyolefin fibrids using suitable dispersing agents. These are obtained by polycondensation of 1 mole of melamine, from 1.8 to 3 moles of formaldehyde and from 0.1 to 0.5 molar portions of amino carboxylic acids or alkali metal salts thereof. Very small quantities of said dispersing agents are sufficient to finely disperse the hydrophobic polyolefin fibrids in water and to prevent the formation of foam in the manufacture of web structures of a paper-like and textile-like nature. The aqueous suspensions of polyolefin fibrids may also contain cellulose fibers.

Abstract: Molding material comprising (a) a specially selected bitumen left as a residue in the distillation of petroleum which has been deacidified with calcium hydroxide and (b) an olefin polymer. The molding material may be pigment-colored and is used in the form of sheeting for insulation in construction.

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.
