4.1.2 Copolymerization Behavior of Nitrogen-Functional Alkenes
Thirteen differently substituted long-chain amide- and amine-functional
comonomers (Fig. 15) were studied in ethylene and propylene copolymerizations
carried out with catalyst rac-Et(Ind) 2 ZrCl 2 (for ethylene) or rac-Me 2 Si
(2-MeInd) 2 ZrCl 2 (for propylene) [22]. As for the oxygen-functional comonomers,
MAO was used as cocatalyst. Amide-functional comonomers were found to depress
the catalyst activity even with high excess of MAO (Al/comonomer 40–80 mol/mol).
Slightly less poisonous were monomers 19 and 20, which contain active hydrogens
