  • Composition based on statistical propylene copolymers, process for their manufacture and multilayer heat-sealable sheets containing them
    Patent number: 5948547
    Abstract: Compositions based on propylene polymers (compositions (C)) comprising:from 68 to 80% by weight of a statistical propylene copolymer (copolymer (A)) which contains from 12 to 20% by weight of units derived from 1-butene and from 0 to 2% by weight of units derived from ethylene, andfrom 20 to 32% by weight of a statistical propylene copolymer (copolymer (B)) which contains from 0 to 15% by weight of units derived from 1-butene and from 1 to 8% by weight of units derived from ethylene.
    Type: Grant
    Filed: December 11, 1996
    Date of Patent: September 7, 1999
    Assignee: Solvay Polyolefins-Europe-Belgium
    Inventors: Raymond Mikielski, Veerle Deblauwe, Mathieu Wilkin
  • Propylene polymers and process for the preparation thereof
    Patent number: 5895803
    Abstract: Statistical propylene copolymer containing 0.2-0.9% by weight monomeric units derived from ethylene; 13-21% by weight monomeric units derived from .alpha.-olefin having 4-10 carbon atoms, and 78.1-86.8% by weight monomeric units derived from propylene. The copolymer has a melting point of 115-125.degree. C.; a proportion of polymer soluble in boiling heptane greater than or equal to 95% by weight, and a proportion of polymer soluble in cold xylene (25.degree. C.) greater than 40% by weight.
