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.
