Methods employing magnetic fields for controlling emulsion polymerization |
摘要 |
Emulsion polymerization with initiators that produce triplet radical pairs is controlled by the application of a magnetic field. Both the rate of polymerization and the molecular weight of the polymer can be controlled. Emulsion polymerization with oil-soluble initiators is enabled to proceed to high conversions at convenient rates and to produce polymers having molecular weights comparable to or higher than those achievable with conventional water-soluble initiators.
