Abstract

Summary: Olefin metathesis polymerization is a flexible and easy way to prepare highly functionalized macromolecules with high precision. Within this context, the efficiency of a series of ruthenium based catalysts in the polycondensation of dienes with diacrylates yielding alternating copolymers is studied. Previous works with Grubbs 2nd generation catalyst are compared with Hoveyda 2nd generation catalyst that was found to be much more efficient in these reactions giving reasonable conversions and thus high molecular weights at low catalyst loading. Additionally the performance of several other Hoveyda type catalysts has been studied.
