  • Propylene polymer and copolymers grafted with vinylpolybutadiene and their preparation process
    Patent number: 5574111
    Abstract: Crystalline propylene (co)polymers modified by grafting with a vinylpolybutadiene having 1,2-structure content of at least 10%.Said (co)polymers are reacted with a liquid vinylpolybutadiene in the presence of a non-peroxidic radical initiator at a temperature in the range 200.degree. to 350.degree. C., the liquid vinylpolybutadiene having a 1.2-structure content of at least 10% and being generally used in amounts within the range 0,5 to 20% by weight.
    Type: Grant
    Filed: June 6, 1995
    Date of Patent: November 12, 1996
    Assignee: Centro Sviluppo Settori Impiego S.r.l.
