TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The unsaturated monomer is chosen from styrene, trifluorostyrene, ( alpha )-methyl styrene, divinylbenzene, chloromethyl styrene, chlorostyrene, vinyl pyridine, acrylic acid, methacrylic acid, vinyl pyrrolidone, vinyl pyridine, vinylacetate, trifluorovinylacetate and/or methyltoluene. Unsaturated monomers containing functional groups, where the functional group is chosen from optionally-substituted aryl and heteroaryl groups, carboxylic acid, carboxylic acid derivatives, amines, amine derivatives, inorganic acid, sulfate, hydroxy and substituted alkyl, cycloalkyl and cycloheteroalkyl groups. The emulsifier is chosen from alkyl sulfate, alkyl sulfonate, alkyl aromatic sulfonate, ethoxylated fatty alcohol, fatty acid ester or their mixtures.    TECHNOLOGY FOCUS - POLYMERS - Preferred Component: The polymer is chosen from polyolefin, fluorinated and per-fluorinated polymer, copolymer and terpolymer, preferably polyethylene, polypropylene, polyhexafluoropropylene, tetrafluoroethylene-propylene copolymer, tetrafluoroethylene-ethylene copolymer, hexafluoropropylene-ethylene copolymer, polyvinylidene halide, polyvinylidene fluoride and polyvinylidene chloride, vinylidene fluoride-tetrafluoroethylene copolymer, polyvinyl fluoride, perfluoroalkoxy copolymer, polyisobutylene acrylic polymers, such as polyacrylate, polymethylmethacrylate, polyethylacrylate, vinyl halide polymers, such as polyvinyl chloride, fluoropolymers such as polytetrafluoroethylene, chlorotrifluoroethylene and fluorinated ethylene-propylene, polyvinyl ether, such as polyvinyl methyl ether, polyacrylonitrile, polyvinylketone, polyvinyl aromatic, and polyvinyl esters, such as polyvinylacetate. Preferred Composition: The content of monomer components of the emulsion is 0.5-45 weight%, preferably 0.5-25 weight%. Preferred Processes: The emulsion is prepared by combining emulsifier with water, adding chain transfer agents, adding monomer and homogenizing. The preparation of graft copolymer further involves functionalization step which involves contacting graft polymer with trimethylamine, triethylamine, N,N,N-trimethylbis(hexamethylene)triamine, and other tertiary, quaternary amine, diamine and triamine and their salts. Preferred Property: The total radiation dose of polymer activation is 1-150 kGy, preferably 30-100 kGy. Preferred Condition: The copolymerization reaction is carried out at 40-90 degrees C, preferably 60-85 degrees C for 0.5-10 hours, preferably 3-8 hours.
