Cycloaliphatic polyolefins with functional groups were prepared by the Pd(II)‐catalyzed addition polymerization of norbornene derivatives. Homo‐ and copolymers containing repeating units based on bicyclo[2.2.1] hept‐5‐en‐2‐ylmethyl decanoate ( endo/exo ‐ratio = 80/20), bicyclo[2.2.1]hept‐5‐ene‐2‐carboxylic acid methyl ester ( exo/endo = 80/20), bicyclo[2.2.1]hept‐5‐ene‐2‐methanol ( endo/exo = 80/20), and bicyclo[2.2.1]hept‐5‐ene‐2‐carboxylic acid (100% endo ) were prepared in 49–99% yields with {(η 3 ‐allyl)Pd(BF 4 )} and {(η 3 ‐allyl)Pd(SbF 6 )} as catalysts. The catalyst containing the hexafluoroantimonate ion was slightly more active than the tetrafluoroborate based Pd‐complex.
