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.
Claims21
A method for forming polar-functionalized polypropylene, the method comprising contacting a propylene monomer and a polar monomer comprising an amine group in the presence of an organozirconium catalyst and in the absence of AlBui3 and/or in the absence of methylaluminoxane, under conditions to induce a polymerization reaction between the propylene and polar monomers, thereby forming polar-functionalized polypropylene.
A method for forming polar-functionalized polypropylene, the method comprising contacting a propylene monomer and a polar monomer comprising an amine group in the presence of an organozirconium catalyst, under conditions to induce a polymerization reaction between the propylene and polar monomers, thereby forming polar-functionalized polypropylene, wherein the polar-functionalized polypropylene is syndiotactic.
