The present invention provides novel polyolefin compositions having variable hardness and/or toughness properties. The polyolefin compositions include: a polyolefin prepared by the metathesis of an olefin monomer using a ruthenium or osmium carbene catalyst; and one or more hardness and/or toughness modulators. The polyolefin is preferably poly(dicyclopentadiene), or poly- DCPD. Also provided are articles of manufacture, such as molded parts, produced from the polyolefin compositions. The disclosed compositions are useful in marine, recreational and sports products.
L'invention concerne des compositions de polyoléfine à dureté et/ou résistance variable, qui comprennent: une polyoléfine obtenue par métathèse d'un monomère d'oléfine, avec un catalyseur au ruthénium ou à l'osmium; et un ou plusieurs modulateurs de dureté et/ou de résistance. De préférence, la polyoléfine est poly(dicyclopentadiène), ou poly-DCPD. L'invention concerne également des produits fabriqués à partir desdites compositions, du type éléments moulés. Les compositions considérées sont utiles pour la fabrication d'articles à usage maritime, récréatif et sportif.
