titleOfInvention | Novel multifunctional azo initiators for free radical polymerizations: uses thereof |
abstract | The invention provides compositions of matter, methods of their synthesis, and methods of their use in polymeriza-tion reactions. The compositions include polyfunctional initiators used to make star polymers when polymerized with monomers. The polyfunctional initiators are synthesized out of a multifunctional core with at least two functional groups and two or more ini-tiator units bonded to the functional groups. The initiator units have two electron-withdrawing groups bonded to a central carbon atom and an azo group between the central carbon atom and the functional group. The polyfunctional initiators are particularly ef-fective because when they decompose to form the radical core of a star polymer, the electron-withdrawing groups prevent the cor-responding radical from forming any linear polymer contamination and only desired star polymers result. In addition when the de-sired star polymers are fed into a reaction vessel by streams with two different concentrations the star polymers produce superior properties. |
