    Abstract: Hydrophilic polyolefin fibers containing inorganic pigments are obtained by means of flash evaporation of a superheated suspension, which is under at least autogenous pressure. The suspension comprises a dispersion of a hydrophobized inorganic pigment in an emulsion prepared from a solution of a polyolefin in an easily boiling solvent and an aqueous solution of a hydrophilizing agent. The suspension is passed through a nozzle into a low pressure zone to form pigmented fibers.

    Abstract: The object of the invention is a process for the preparation of olefin polymers using a modified Ziegler catalyst. As modifications compounds are used which contain as the only functional groups one or two tertiary carboxylic acid amide groups or a urea grouping four times substituted at the nitrogen atoms. Polymers are obtained which confer special mechanical properties on the molded articles prepared therefrom.

    Abstract: 1339332 α-Olefin polymerization FARBWERKE HOESCHST AG 5 Nov 1971 [7 Nov 1970] 51582/71 Heading C3P α-Olefins CH 2 = CHR where R is aliphatic with 1 to 4 carbon atoms are polymerized by themselves or with up to 5% by weight ethylene or block polymerized by themselves or with up to 25% by weight ethylene in suspension or in the gas phase at temperatures of 20‹ C. to 130‹ C. and gauge pressures of 0 to 50 atmospheres in the presence of a catalyst comprising (a) a phosphoric acid N alkylamide O = P(NR 2 ) 3 where the groups R may be the same or different hydrocarbon radicals having up to 4 carbon atoms and may be linked to other R groups, (e.g. hexaethyl or hexamethyl trisamide of phosphoric acid or phosphoric acid trisethyleneimide) (b) a cyclopolyalkene with 7 or 8 ring members and 2 to 4 non-cumulative double bonds in the ring or alkyl or alkoxysubstituted derivatives thereof having 1 to 4 carbon atoms in the alkyl radical (e.g. 1, 3, 5 cycloheptatriene, norcaradiene, cyclooctatriene or cyclooctatetraene) (c) a halogen containing compound of trivalent titanium and (d) a halogen free organoaluminium compound. In the examples propylene is polymerized in the presence and absence of preformed polypropylene using as catalyst TiCl 3 1/3 AlCl 3 , triethylaluminium, phosphoric acid hexamethyl trisamide and 1,3,5 cycloheptatriene or cyclooctatetraene. In Example 15 the product is treated with propanol and washed with acetone. Reference has been directed by the Comptroller to Specifications 920, 118, 1,018,341 and 1,254,016.
