Patent

CA 2341588

Novel high melt flow polypropylene compositions useful in the manufacture of fibres and films are disclosed. The novel polypropylene compositions contain effective stabilizing amounts of selected N,N-dialkylhydroxylamines and organic phosphites or phosphonites which provide for a reduction in the amount of smoke, oil and wax generated when such compositions are spun or extruded into fibers or films.

L'invention concerne de nouvelles compositions de polypropylène à indice de fusion élevé, utiles dans la fabrication de fibres et de films. Les nouvelles compositions de polypropylène contiennent des quantités efficaces du point de vue d'une stabilisation, de N,N-dialkylhydroxylamines sélectionnées et de phosphites ou de phosphonites organiques qui permettent de réduire la quantité de fumée, d'huile et de cire produite lorsque ces compositions sont filées ou extrudées pour former des fibres ou des films.
