  • Composition based on polyolefins and on ethylene-vinyl acetate copolymer
    Patent number: 6258862
    Abstract: A composition including, by weight: from 40 to 80% of at least one uncrosslinked composition (A) including at least one polyolefin (PA); from 60 to 20% of at least one crosslinked composition (B) including at least one propylene polymer (PB) and at least one ethylene-vinyl acetate (EVA) copolymer. The composition B has preferably been obtained beforehand by processing a composition including from 10 to 49% of at least one propylene polymer (PB), from 90 to 51% by weight of at least one ethylene-vinyl acetate copolymer, and from 100 to 1500 ppm by weight of at least one crosslinking agent. This composition makes it possible especially to manufacture foam sheets which can be employed in the motor vehicle industry, which are thermoformable, HF weldable and recyclable.

    Assignee: Solvay (Société Anonyme)
    Inventors: Pierre Matz, Edmond Mulkens
  • Compositions based on propylene polymer and ethylene-vinyl acetate copolymer, process for their conversion, sheets obtained from these compositions
    Patent number: 6100335
    Abstract: Compositions based on propylene polymer, ethylene-vinyl acetate copolymer and organic peroxide, characterized in that they include, by weight:a) 10 to 49% of at least one propylene polymer;b) 90 to 51% of at least one ethylene-vinyl acetate copolymer in which the vinyl acetate content is from 12 to 40% by weight;c) between 50 and 1000 ppm (parts per million) of at least one organic peroxide. The sheets obtained by extrusion of these compositions can be employed for the internal trim in the motor vehicle industry.

  • Moulding compositions comprising polyolefins and cellulose fibres, process for their manufacture and objects wrought from these compositions
    Patent number: 5164432
    Abstract: Moulding compositions comprising a polyolefin, cellulose fibres and an unsaturated organosilane exhibiting a tensile elasticity modulus (E), measured at 100.degree. C., higher than 1250 MPa and a ratio G'/G" of their modulus G', representing their elastic response, to their loss modulus G", measured at 200.degree. C. and at a frequency of 0.1 rad/s (0.1 s.sup.-1), with a value of at least 0.80.
