ABSTRACT:
Method for preparing a polyolefin modified by grafting, in which in a first phase, peroxides are grafted in known manner onto a polyolefin chain with a mixture of oxygen and ozone, wherein, in a second phase, a vinyl monomer with at least one epoxy function is added to the resulting peroxidized polyolefin, and in a third phase, the resulting mixture is polymerized.
The invention finds an application in the preparation of polypropylene with excellent adhesive properties especially with iron, leather and glassfibers.
