The polymerization of monomers containing functional groups is of great interest due the resulting variety of chemical and physical properties. The use of group of IV catalyst systems to polymerize alpha-olefins containing functional groups is limited by the tolerance of the catalyst systems to the functional groups. Investigation of the interaction of phosphines and the activated titanium phosphinimide catalyst systems[1] has lead to the design of alpha-olefins containing sterically bulky phosphine groups and the homo- and co-polymerizations of these monomers. Additionally, the subsequent derivatization of these polymers will be detailed.
