Abstract

The present invention relates to a new manner of grafting various organic groups or polymers; it is concerned particularly with the grafting of vinyl, acryl, vinylidene or other chains on polymers of olefines, diolefines, aromatic vinyl compounds and similar compounds; a new catalytic system is used for effecting such a grafting, wherein a deactivated polymer is brought into contact with at least one organometallic compound and at least one generator of free radicals out of the presence of air.
