The modification of polyolefi ns by polar monomers in the melt and solid state on one extruder was investigated. The features of changes in the physical and chemical properties of polyolefi ns with melt and solid modifi cations are studied. The reactivity of comonomers in liquid-phase and solid-phase modifi cation processes has been compared. The method of grafting solid modifi cation, in which pre-ozonated polyethylene is used as a copolymerization initiator, has been investigated. High adhesion properties of the copolymers were found.
