Ring-opening metathesis polymerization (ROMP) is utilized for the synthesis of highly functionalized polymers with covalently bound chiral prolinol units. The linear macromolecules act as multifunctional ligands in homogeneous asymmetric catalysis. The solubility of the polymers and their catalytic performance can be tuned by random copolymerization with achiral units in a simple and flexible manner. Use of norbornenes with additional well-defined stereogenic centers in the polymerizable core of the monomers leads to polymers which show cooperative effects between the various elements of chirality during the course of the catalysis.
