This work explores how various polythiophenes copolymers can be synthesized via Kumada catalyst transfer polymerisation, demonstrating that the accurate kinetic measurements of thiophene monomers enable reliable predictions of copolymer structures.
The ketimide half-titanocene catalysts 1–3 yielded high molar mass propene-norbornene copolymers (P-co-N) with efficient N incorporation and tensile properties ranging from ductile and tough materials to stiff and fragile ones as N content increases.
Using a highly active supported permethylindenyl-phenoxy (PHENI*) titanium catalyst, high molecular weight ethylene–propylene (EPM) and and ethylene–propylene–diene (EPDM) elastomers are prepared with tuneable compositions using slurry-phase catalysis.
Cyclic esters chain shuttling copolymerization between yttrium and aluminum catalysts is reported for the first time. It allows to tune the thermal properties of the resulting copolymers.
Experimental and computational studies show how cationic Zr complexes dictate homopolymer or copolymer formation in olefin and lactone polymerisation.
