Vinyl-terminated macromonomer oligomerization, namely, a process to produce polymacromonomers comprising contacting a vinyl-terminated macromonomer with a catalyst system capable of oligomerizing vinyl-terminated macromonomer, in the presence of an aluminum containing compound, a zinc containing compound, or a combination thereof, under polymerization conditions to produce a polymacromonomer, and polymacromonomers produced thereby. Also, polymacromonomers having a degree of polymerization greater than 10, a glass transition temperature Tg of less than 60&#xb0; C., and an Mn of greater than or equal to about 5000 Da.
