Abstract Propylene copolymers with different polar groups were synthesised using <I>rac</I>-Et[1-Ind]<SUB>2</SUB>ZrCl<SUB>2</SUB>/MAO as the catalyst system. 10-Undecen-1-ol, 10-undecenoyl chloride, 10-undecenoic acid, 2-(9-decen-1-yl)-1,3-oxazoline, 2-(9-decen-1-yl)-4,4-dimethyl-1,3-oxazoline, and 2-[4-(10-undecene-1-oxy)phenyl]-1,3-oxazoline were used as comonomers. The addition of water to the 10-undecenoyl chloride copolymer solution led to an acid-functionalised copolymer. In the case of 2-(9-decen-1-yl)-1,3-oxazoline and its homopolymers, polymerisation temperature was varied. Up to 0.61 mol-% comonomer were incorporated into the poly(propylene)s. The catalyst activities for 10-undecen-1-ol, 10-undecenoyl chloride and 10-undecenoic acid were much higher than for the oxazoline comonomers.
