  • Semicrystalline propylene polymer compositions with good suitability for producing biaxially oriented films
    Patent number: 6593442
    Abstract: A semicrystalline propylene polymer composition with good suitability for producing biaxially oriented films and prepared by polymerizing propylene, ethylene and/or C4-C18-1-alkenes, where at least 50 mol % of the monomer units present arise from the polymerization of propylene. Also described is the use of the semicrystalline propylene polymer composition for producing films, fibers or moldings, the films, fibers and moldings made from these compositions, biaxially stretched films made from the semicrystalline propylene polymer compositions, and also a method for characterizing the semicrystalline propylene polymer compositions.

  • Partly crystalline propylene polymerisate composition for production of biaxial-stretched polypropylene films
    Publication number: 20030130443
    Abstract: The present invention relates to a semicrystalline propylene polymer composition prepared by polymerizing propylene, ethylene and/or C4-C18-1-alkenes, where at least 50 mol % of the monomer units present stem from the polymerization of propylene and at least 20% by weight of the propylene polymer composition is the result of a polymerization using metallocene catalysts,

  • Production of carotenoid preparations in the form of coldwater-dispersible powders, and the use of the novel carotenoid preparations
    Patent number: 5968251
    Abstract: Carotenoid preparations in the form of coldwater-dispersible powders are produced bya) preparing a molecular-disperse solution of a carotenoid, with or without an emulsifier and/or an edible oil, in a volatile, water-miscible, organic solvent at elevated temperature and adding therein an aqueous solution of a protective colloid, whereupon the hydrophilic solvent component is transferred into the aqueous phase, and the hydrophobic phase of the carotenoid results as nanodisperse phase,b) heating the resulting hydrosol at from 40.degree. C. to 90.degree. C., with or without cooling of the hydrosol to from 0.degree. C. to 30.degree. C. beforehand, andc) removing the solvent and the water from the heated hydrosol, and converting it into a water-dispersible dry powder.
