  • Production of olefin dimers and oligomers
    Publication number: 20030225307
    Abstract: Disclosed is an olefin containing stream from an oxygenate to olefin process, and a process for making olefin dimer and oligomer product from the olefin containing stream using a nickel based oligomerization catalyst. The dimer/oligomer product is optionally converted to hydroformylated product. The olefin containing stream that is used to make the higher olefin product has low levels of impurities including nitrogen, sulfur and/or chlorine.
    Type: Application
    Filed: April 29, 2003
    Publication date: December 4, 2003

  • Master batch for use in the production of bi-axially oriented polyalkylene films
    Patent number: 5969007
    Abstract: The invention is directed to a masterbatch for the production of biaxially oriented polyalkylene films which, based on the total amount, contains in a matrix of polyalkylene homopolymer or copolymer from 1 to 50% by weight of spherical solid silicate particles and optionally, from 0.1 to 15% by weight of a surface-modifying reagent which reacts with the surface of the silicate, thus improving the adherence between the silicate and the polyalkylene. The invention is also directed to a process for the production of such a masterbatch, its use in the production of biaxially oriented polyalkylene films, and to biaxially oriented, co-extruded multilayer polyalkylene films.
