Název v původním jazyce

Chain-end functionalization of polyolefins prepared by alpha-diimine nickel catalysts using transfer to organometallic compounds

Popis výsledku v původním jazyce

A method for chain-end functionalization is described for branched polyolefins obtained by living olefin polymerization initiated by α-diimine nickel catalysts. The method relies on transmetalation of living polymer chains from nickel growing centres to excess organozinc, organomagnesium or organoaluminium transfer agents followed by oxidation. Hydroxy-terminated polyolefins were obtained with efficiencies going from 25 to 99%. The resulting end-functionalized polyolefins were characterized by MALDI-TOF MS and employed as macroinitiators for ring opening polymerization of ε-caprolactone to provide amphiphilic block copolymers.
