Summary: ω ‐Styryl‐polystyrene macromonomers were synthesized by anionic induced deactivation reactions. Their homopolymerization in the presence of a fluorinated half‐sandwich metallocene catalyst (CpTiF 3 /MAO) was investigated. In spite of the intrinsic lower reactivity of these macromonomers with respect to the micromolecular monomer, coordination homopolymerization was possible. The influence of several experimental parameters on the polymerization yield and degree could be demonstrated. In most cases, under identical experimental conditions, higher polymerization yields and degrees were observed with respect to the CpTiCl 3 /MAO catalyst.The synthesis of p ‐polystyryl‐substituted styrene derivatives by the homopolymerization of ω ‐styryl‐polystyrene macromonomers in the presence of CpTiF 3 .
