Bridged metallocenes called Kaminsky catalysts make them with one type of tacticity, while traditional Ziegler-Natta catalysts give the other form.
One scientist applied Kuhn's excluded volume to these compounds and developed the idea of the "theta solvent," for which it is minimized. A coordinate convention used for this type of compound is named for that man, Paul Flory. "Living" reactions to make these are often controlled by redox equilibria. Bridged metallocenes called Kaminsky catalysts make them with one type of tacticity, while traditional Ziegler-Natta catalysts give the other form. Initiation, elongation, and termination steps are essential to the radical mechanism for forming these. For 10 points, name these compounds exemplified by plastics, formed by repeated addition of units called monomers.
