摘要： A polypropylene molding composition having an excellent impact strength at a temperature down to -60.degree. C and simultaneously a good hardness contains from 70 to 90% by weight of a polypropylene, 2 to 10% by weight of an ethylene propylene copolymer and 8 to 25% by weight of a polyethylene and is distinguished by a melt index MFI 230/5 lower than that of the polypropylene contained therein and simultaneously higher by the coefficient 1.3 to 7.0 than that of a polypropylene prepared in the presence of the same catalyst as the molding composition and having the same RSV.

摘要： 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.

摘要： Oxymethylene polymers (POM) are obtained in granular form by cooling a POM solution or dispersion having a temperature above the sintering temperature of the POM in two stages to a temperature just below the said sintering temperature. The solvent or dispersion agent used is a mixture of methanol and water and the cooling agent is a methanol/water mixture which may contain POM suspended therein. The granular POM obtained is suitable as technical material for making shaped articles.
