Abstract
Methods for forming polar-functionalized isotactic and syndiotactic polypropylenes are provided, including amino-functionalized polypropylene. In embodiments, such a method comprises contacting a propylene monomer and a polar monomer comprising an amine group in the presence of an organozirconium catalyst and in the absence of a masking reagent, under conditions to induce a polymerization reaction between the propylene and polar monomers, thereby forming polar-functionalized polypropylene.
