Improved processes based on atom (or group) transfer radical polymerization and novel (co)polymers having useful structures and properties

Gradually or (group) transferring free polymerization ATRP (a) improvement method of the compound. A separate of solution, the ATRP a method of (a) the free group of inactivating a transition metal compound of the reducing or oxidation 4-methoxy the polymerization. The other of solution, the method ATRP relates to the homogeneous or system, wherein solubilization of serotonin/catalytic system is present of the polymerization. The invention further relates to a functional, the position with function and far chela homopolymer and copolymer,A a certain performance or a novel structure block, FORMULA, graft, and a composition of ratio (or and “”) copolymer,The star-shaped compound, the substitutes a and a high the preparation of polymer or copolymer,Multifunctional high polymer, a functionalized polymer,cross-linked polymer and gel; The water-soluble polymer and hydrogel (e.g. a copolymer of the monomer and second ethylene monomer of the copolymer is formed); The use of the water and medium the method ATRP.
