Abstract: The invention relates to polyolefin fibrils which have been modified by means of an oxide, hydroxide or silicate of an element from main group II to IV of the periodic table or a sub-group element. They have a high degree of beating and a large specific surface area and are particularly suitable as asbestos substitute. They are prepared from solutions of the polyolefins in an organic solvent which contain the admixed modifier, in a process in which the solutions are either a) heated under pressure and cooled under adiabatic relaxation, during which the fibrils are deposited, or b) introduced into a precipitation bath under the action of shear forces, during which the fibrils precipitate.

Abstract: Si (80-99% purity and particle size 0.1-100 mu m) dispersed in an inert org. diluent is reacted with various alcohols or phenols (pref. EtOH; MeOH is most rapid) at 20-300 degrees (pref. 100-200 degrees) and 0-25 atm. gauge, and the alkoxy- or phenoxy- substd. silane hydride obtained is reacted with an unsatd. organic cpd. at 20-360 degrees (pref. 80-150 degrees) and 0-200 atm. gauge. The first reaction is pref. carried out in the presence of soluble cpds. Of cu, Ni, Zn, Ag, fe, Pt, Ti, Sn or Zr. The process does not involve the intermediate formation of organochlorosilanes and the expensive recovery of anhyd. HCl.

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: Concrete compositions are prepared from cement, water, an optional aggregate and particles of expanded styrene polymers whose surfaces are coated with an organosiloxanol of formula where n is an integer from 1-250, R is a C1-C6 alkyl or alkenyl group or an aryl group. The styrene may be copolymerized with acrylonitrile, acrylic or methacrylic esters of C1-C8 alcohols, N-vinyl compounds, e.g. N-vinyl carbazol and divinylbenzene. Aggregates specified are sand, pumice, vermiculite and asbestos.

Abstract: These comprise (A) bitumen and (B) olefin polymerisates in a wt. ratio of 1:0.05 to 0.05:1. They also contain (C) 0.5-30 wt.% sulphur and are vulcanised with the aid of 0.05-5 wt. % of a vulcanisation accelerator. The compns. may also contain 2-70 wt. % of a filler, 0.05-50 wt. % of a basic materiale.g. cement and 0.01-2 wt. % of a peroxide.
