Abstract

Olefinic polymers characterized by the presence of free carboxylic groups arranged along the polymeric chain, obtained by radicalic grafting of unsaturated carboxylic acids onto the chain of the olefinic polymer. The products so obtained exhibit in particular a high adhesion to metals. The manufacturing process is based on the use of at least two different organic peroxides, having different reactivities.
