  • Elastomeric composition comprising a functionalized elastomer
    Patent number: 7015277
    Abstract: An elastomeric composition vulcanizable with sulfur and/or sulfur donors useful for the preparation of tyres, which comprises: a) 100 parts of an elastomeric mixture comprising from 20 to 100% by weight, preferably from 60 to 100% by weight, of a functionalized elastomer (a1), from 0 to 80% by weight of a non-functionalized elastomer (a2) selected from monovinylarene-conjugated diene statistic copolymers, natural rubber, polybutadiene: b) from 10 to 150 parts of silica per 100 parts of (a); c) from 0 to 150 parts of carbon black per 100 parts of (a).
    Type: Grant
    Filed: November 7, 2001
    Date of Patent: March 21, 2006
    Assignee: Polimeri Europa S.p.A.

  • Process for the functionalization of polyolefins
    Publication number: 20050113518
    Abstract: Process for the preparation of functionalized polyolefins, which comprises treatment under shear conditions of said polyolefins with an unsaturated monomer containing polar groups in the presence of at least one hydroperoxide as radicalic initiator. The process allows the grafting of unsaturated monomers without the formation of cross-linked polymeric material and without modifying the molecular weight distribution.
