What is Homo- and Copolymerization of ω-Functional Polystyrene Macromonomers via Coordination Polymerization about?

## Abstract Macromonomers have been extensively used, as well defined building blocks for various macromolecular architectures via anionic, ROMP and free radical homo‐ or copolymerization processes. The purpose of the present work was to examine the homopolymerization and copolymerization of __ω__‐allyl, __ω__‐undecenyl and __ω__‐vinylbenzyl polystyrene (PS) macromonomers, in the presence of early or late transition metal catalysts. The influence of several parameters (type of catalytic system, nature of polymerizable end‐group and molar mass of the macromonomer) on the homopolymerization was first investigated. Whereas __ω__‐allyl or __ω__‐undecenyl PS macromonomers were not very reactive in homopolymerization whatever the catalyst, __ω__‐vinylbenzyl PS macromonomers gave interesting results with CpTiCl~3~/MAO and Cp\*TiCl~3~/MAO. The copolymerization of these macromonomers with ethylene was also studied in the presence of the following palladium catalyst: [(ArNC(Me)C(Me)NAr)Pd(CH~2~)~3~(COOMe)]^+^BAr~4~′^−^(VERSIPOLTM) (Ar = 2,6‐__i__Pr~2~–C~6~H~3~ and Ar′ = 3,5‐(CF~3~)~2~C~6~H~3~). __ω__‐vinylbenzyl PS macromonomers could not be incorporated into poly(ethylene) chains.
