Title:
CONTROL AGENTS FOR LIVING-TYPE FREE RADICAL POLYMERIZATION, METHODS OF POLYMERIZING, EMULSIONS AND POLYMERS WITH SAME
Document Type and Number:
WIPO Patent Application WO2002026836
Kind Code:
A3
Abstract:
Control agents that have a nitrogen-nitrogen bond covalently bonded to a thiocarbonyl moiety are provided for living-type free radical polymerization of a wide variety of monomers. These control agents provide superior properties for control of the polymerization and/or the properties of the polymers obtained and/or the monomers that may be polymerized. In some embodiments, a bulky group is pendant off the activated thiocarbonyl portion of the control agents. Multifunctional control agents provide the opportunity for a variety of structurally unique polymers, including block copolymers, stars and hyper-branched polymers.
