Abstract
A method for forming polar-functionalized polyolefins may comprise contacting an unsubstituted α-olefin monomer and an amino-olefin monomer of formula HC═CH(CH)(CHR)NR', wherein R is H or an unsubstituted linear or branched alkyl group having from 1 to 10 carbons, each R′ is an independently selected unsubstituted linear or branched alkyl group having from 1 to 10 carbons, m is an integer from 1 to 11, and n is an integer from 1 to 11, in the presence of a rare earth catalyst and a cocatalyst under conditions to induce a heteropolymerization reaction between the unsubstituted oc-olefin and amino-olefin monomers to provide a polar-functionalized poly olefin.
