Research topics

Research is oriented towards synthesis of tailor-made polymers with defined chain length, molar mass distribution, branching of chain, end-groups, polymer topology and polymer stereoregularity using the methods of living/controlled polymerizations.

Catalyst development and synthesis of novel polyolefin based materials is investigated.

Living/Controlled catalytic polymerizations of olefins

Preparation of tailor-made polyolefins by diimine catalyzed olefin polymerizations with control over molar mass and its distribution, branching degree. Kinetic and mechanistic investigation of polymerization. DFT modeling of active centers. Morphology Control (in collaboration with prof. Cramail, University Bordeaux).
