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: Appts. for producing fibrils, by introducing a soln. of a polymer into a liquid precipitating medium, has a rotor rotatably mounted in a housing; an axial inlet for the precipitating medium; and inlets for the polymer soln. Radial passages are arranged in the peripheral part of the housing, and the inlets for the soln. are arranged in the vicinity of the inlet position of the precipitating medium into the radial passages. Operates reliably without stoppages for long periods. Gives high quality fibrils having a uniform size and shape with a relatively low energy consumption. The fibrils can be converted into fleeces having a good initial wet strength.
