WebSep 12, 2024 · The formation of coordination compounds is one of many important aspects of inorganic chemistry. In a coordination compound, an electron pair donor, called a ligand, shares its electron pair with a metal atom. Frequently, the metal atom is a transition metal, and very commonly it is a transition metal ion, but there are other examples as well. WebA new diblock copolymer of propene and methyl methacrylate (MMA) was prepared by adding MMA during the living coordination polymerization of propene together with the soluble catalyst V(acac) 3 /Al(C 2 H 5) 2 Cl at −78°C and subsequently by raising the polymerization temperature up to 25°C. The homopolymerization of MMA with this …
