A polyolefin polymer comprising one or more terminal polymerizable methacryloyl groups (i.e. tethered to the main body of the polymer) and a novel process for preparing same are herein disclosed. A hyperbranched polyethylene polymer and a process for preparing same are also disclosed. The polymer is prepared by a novel one-pot copolymerization reaction of an olefin, such as ethylene, and a heterobifunctional comonomer comprising a methacryloyl group, catalyzed by a late transition metal alpha-diimine catalyst which is selectively non-reactive towards methacryloyl groups. The process allows for preparation of polymers with various chain topologies, including linear, branched, and hyperbranched topologies. The terminal methacryloyl groups within the polymer are reactive in further polymerization reactions. Thus, the polymer may be used in materials and applications which require cross-linking or further polymerization, for example, UV/thermal/radical curable crosslinkers for use in thermoset applications.
