PROCESSO DI PRODUZIONE DI UNA PALIOLEFINA MODIFICATA CON UN MANOMETRO POLARE

The present invention relates to the process of the grafting of monomers onto polyolefins in the presence of organic peroxides, whereby the monomer(s) and organic peroxide have been absorbed into a carrier polymer that, under the grafting conditions, undergoes chain scission in preference to cross-l...

Beschreibung
Zusammenfassung:	The present invention relates to the process of the grafting of monomers onto polyolefins in the presence of organic peroxides, whereby the monomer(s) and organic peroxide have been absorbed into a carrier polymer that, under the grafting conditions, undergoes chain scission in preference to cross-linking in the presence of organic peroxides. The described grafting process allows to obtain an impact-modified graft-polyolefins useful as adhesives to polar polymers, metals, epoxy resins, cellulosic substrates and other polyolefins. Moreover, the described grafting process allows to obtain impact-modified, grafted polyolefin compounds with improved extrudability, heat stability and reduced gels or imperfections.
