A group of compounds defined by formula (I) can be used to anionicly initiate the polymerization of unsaturated monomers. In the formula, M is an alkali metal atom, R 1 is an aryl group having at least one OR 2 substituent, where each R 2 is unreactive to M, and R is a hydrocarbyl group. Subject initiators can be used in semi-batch and continuous polymerization processes, even in processes carried out at elevated temperatures. |
