08973 IUPAC Gold Book - controlled ionic polymerization 10.1351/goldbook.08973 08973 current 1 Term indicating control of a certain kinetic feature of an ionic polymerization or structural aspect of the polymer molecules formed by ionic polymerization, or both. Generally, the adjective 'controlled' should not be used without specifying the particular kinetic or structural feature that is subject to control. The term controlled ionic polymerization is sometimes used to indicate that the initiation is complete within a period that is short with respect to that for propagation such that dispersities are very low and the molar mass can be precisely predicted based on the initial reagent concentrations. controlled polymerization https://goldbook.iupac.org//terms/view/08908 PAC, 2022, 94, 1093.
