Abstract
Processes of polymerizing polyolefins and synthesis of activators. The polymerization processes include polymerizing one or more (C-C)α-olefin monomers in the presence of at least one catalyst and at least one co-catalyst to produce a polyolefin. The co-catalyst includes a cation and an anion, in which the anion has a structure having a vinyl terminated alkene, one boron atom or more than one boron atoms, and at least four halogen atoms. The anion of the co-catalysts is incorporated into a polymer chain of the polyolefin.
