Kinetics of anionic polymerization of β‐myrcene in hydrocarbon solvents
Polymer International, EarlyView.The process of anionic polymerization of β‐myrcene in hydrocarbon solvents was examined by kinetic studies and quantum chemical calculations. Abstract The kinetics of anionic polymerization of β‐myrcene initiated by sec‐butyllithium were examined in saturated and unsaturated hydrocarbon solvents, i.e. cyclohexane, cyclohexene, 4‐vinylcyclohexene and dl‐

Olefin Polymerizations Oriented by Rational Designs of Group‐13 Compounds
The Chemical Record, EarlyView.In coordination olefin polymerization chemistry, boron and aluminum compounds play important roles in both catalyst components and monomers. This personal account introduces our recent progress on the development of catalyst systems featured by the design of group‐13 counteranions, as well as the application of boronic acid‐crosslinked polyolefins to ...
