    Abstract: THE PRESENT IVENTION RELATES TO THERMOPLASTIC MOULDING COMPOSITIONS, CONSISTING OF TWO COMPONENTS IN A DETERMINED MIXING RATIO, ONE COMPONENT BEING POLYETHYLENE HAVING A MELT INDEX I2 (AT 190*C.) WITHIN THE RANGE OF FROM 0.4 TO 80 AND THE OTHER COMPONENT BEING A SEQUENCED COPOLYMER OF PROPYLENE AND ETHYLENE HAVING A MELT INDEX I10 (AT 190*C.) WITHIN THE RANGE OF FROM 0.5 TO 60. FURTHERMORE, THE PRESENT INVENTION PROVIDES A PROCESS FOR THE MANUFACTURE OF THESE MOULDING COMPOSITIONS. THE MIXTURES IN ACCORDANCE WITH THE INVENTION CAN BE PROCESSED TO SHAPED ARTICLES WHICH ARE DISTINGUISHED BY AN IMPROVED IMPACT STRENGTH AT LOW TEMPERATURES AND AN IMPROVE TRANSPARENCY, WHILE HAVING SUBSTANTIALLY THE SAME HARDNESS.

    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: A process is described for the preparation of mixtures for processing as plastisols or organosols, wherein at least one known plasticizer, at least one first vinyl chloride copolymer and at least one vinyl chloride homopolymer or a second vinyl chloride copolymer are mixed together, if appropriate with the addition of further known substances. The first copolymer is a specific vinyl chloride graft copolymer, of which 5 to 70% by weight are employed, relative to the total quantity of polymers present in the mixture. It contains 99.5 to 88% by weight of polymerized units of vinyl chloride, 0.1 to 11.9% by weight of polymerized units of vinyl acetate and 0.1 to 2.2% by weight of polymerized units of ethylene. The remaining polymer(s) employed is/are prepared in accordance with customary processes. Mixtures prepared in this manner produce plastisols or organosols which have a low viscosity and good stability on storage and which also enable uniform coatings to be obtained by applying a thin layer.
