Abstract
Functionalized polymers obtained from metallated crystalline copolymers of one or more alpha-olefins with minor proportions of a diene by reaction with monomers polymerizable of anionic methods or with compounds that react with the metallated copolymer. The metallated copolymer is obtained by reaction of the olefin copolymer with organometallic compounds of lithium, in suspension in an inert solvent. The lithiation stage and the subsequent polymer modification reaction take place in inert hydrocarbon suspension at a temperature below that of the swelling point of the starting copolymer.
