Polyolefins are the major commodity polymers. Their annual production is around 170 million tons per year and their annual growth rate of around 3-4% is remarkable. This family alone represents more than 60% of plastic production.
Although the polymerization catalysis of olefins has been based, since the 1950s, on the heterogeneous Ziegler-Natta (titanium) and Phillips (chromium) catalysts, the existence of several active species is a limitation for certain applications of olefins. The use of well-defined molecular complexes makes it possible to produce « tailor-made polyolefins » with original properties or improved mechanical performances.
My research aims at developing olefin and conjugated dienes polymerization catalysts in homogeneous and heterogeneous media. The challenge is not only to develop well-defined molecular catalysts for the production of advanced polyolefins, but also to adapt them to heterogeneous industrial processes that require supported catalysts. As technology transfer to industry is a key issue, process parameters are taken into account in chemical studies.

Most of my present project are linked to the joint laboratory with the Michelin : ChemistLab. This interdisciplinary laboratory masters a global chain of knowledge combining chemistry and reaction engineering to design, synthesize and evaluate the physicochemical and mechanical properties of new elastomers.
