This paper discusses a new functionalization approach, involving p-methylstyrene (p-MS) "reactive" comonomer. Comparing with other relative styrenic comonomers, i.e. styrene, o-methylstyrene and m-methylstyrene, p-MS shows significantly higher reactivity in metallocene catalysis. The resulting co-and ter-polymers, covering from semicrystalline thermoplastics (PE) to amorphous elastomers (EP and EO), exibit narrow composition and molecular weight distributions. In turn, the incorporated p-MS units in polyolefins, are very versatile, which not only can be interconverted to various functional groups, such as -OH, -NH2, -COOH, anhydride, silane and halides, but also can be conviniently transformed to "stable" aniomc initiators for "living" anionic graft-from polymerization reactions. Many new functional polyolefin graft copolymers have been prepared, containing polyolefin backbone (PE, EP, EO, etc.) and functional polymer side chains, such as PMMA, PAN, PS, etc..
