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 chain-walking   polymerizations of olefins to control molar mass and its distribution, branching degree, stereoregularity and polymer topology.

Preparation of block copolymers, morphology control. Kinetic and mechanistic investigation of polymerization.
