Keggin structure James F. Keggin, the discoverer of the Keggin Structure. Keggin structure. The Keggin structure is the best known structural form for heteropoly acids.It is the structural form of α-Keggin anions, which have a general formula of [XM 12 O 40] n −, where X is the heteroatom (most commonly are pentavalent phosphorus P V, tetravalent silicon Si IV, or trivalent boron B III), M ...
In polymer chemistry, ring-opening metathesis polymerization (ROMP) is a type of chain-growth polymerization involving olefin metathesis. [1] The reaction is driven by relieving ring strain in cyclic olefins. [2] A variety of heterogeneous and homogeneous catalysts have been developed for different polymers and mechanisms. [3]
