Definition
Term indicating control of a certain kinetic feature of an anionic polymerization or structural aspect of the polymer molecules formed by anionic polymerization, or both.

Notes
1) Generally, the adjective 'controlled' should not be used without specifying the particular kinetic or structural feature that is subject to control.
2) The term 'controlled anionic polymerization' is sometimes used to indicate that the initiation is complete within in a period that is short with respect to the time for propagation such that dispersities are very low and the molar mass can be precisely predicted based on the initial reagent concentrations.
