  • Patent number: 6881493
    Abstract: Uses of syndiotactic/atactic block polypropylene are provided in which the molecular weight thereof is preferably at least 120kD. The syndiotactic/atactic block polypropylene may be used as a polypropylene modifier, a component in an adhesive composition, a shock absorber component, a waterproof membrane component, a packaging film or component thereof, a shapable composition component, and an acoustic absorbent material component, a composition for moulding into a footwear component, a bitumen modifier, a compatibiliser, an emulgator or an emulsifier, as a viscosity improver, and as a spilled oil absorber.
    Type: Grant
    Filed: October 9, 2001
    Date of Patent: April 19, 2005
    Assignee: ATOFINA Research S.A.
    Inventors: Bernard Haveaux, Thierry Coupin
  • Patent number: 6538053
    Abstract: Bituminous compositions modified with self-adhesive cold-application polymers generally used for manufacturing of watertight roofing panels, said compositions comprising a mixture containing a rubbery styrene-diene polymeric mixture, one or more tackifying resins, and bitumen.
    Type: Grant
    Filed: September 18, 2000
    Date of Patent: March 25, 2003
    Assignee: Fina Research S.A.
    Inventors: Bruno Drieskens, Bernard Haveaux
  • Publication number: 20020055561
    Abstract: Uses of syndiotactic/atactic block polypropylene are provided in which the molecular weight thereof is preferably at least 120 kD. The syndiotactic/atactic block polypropylene may be used as a polypropylene modifier, a component in an adhesive composition, a shock absorber component, a waterproof membrane component, a packaging film or component thereof, a shapable composition component, and an acoustic absorbent material component, a composition for moulding into a footwear component, a bitumen modifier, a compatibiliser, an emulgator or an emulsifier, as a viscosity improver, and as a spilled oil absorber.

    Inventors: Bernard Haveaux, Thierry Coupin
  • Patent number: 6235817
    Abstract: The present invention relates to bituminous compositions used for roofing and waterproofing membranes or material comprising asymmetrical coupled polyvinyl aromatic-polydiene block copolymers having improved physical properties over broader ranges of service temperatures than those obtained from bituminous compositions prepared with symmetrical block copolymers of similar type. The asymmetry of the copolymer which is characterised by polyvinyl aromatic endblocks of at least two different molecular weights, one high and one low, ensures improved physical performance to roofing and waterproofing membranes made from such compositions.
