Anionic Polymerization
... The range of useful solvents for anionic polymerization is limited by the high reactivity (basicity and nucleophilicity) of the initiators and propagating carbanionic chain ends. For styrene and diene monomers, the solvents of choice are alkanes, cycloalkanes, aromatic hydrocarbons, and ethers [3, 3 ...
