摘要:A method is provided for the direct synthesis by living cationic polymerization of novel polymeric materials functionalized with desirable nitrogen-containing functional groups such as terminal azido, cyano, carbonylamino, cyanato, thiocyanato or thiocarbonylamino groups. Polymerization and functionalization occur in a substantially simultaneous manner. All necessary reactants for the functionalization are present when polymerization is initiated. The nitrogen-containing functional group is provided as a part of a molecule having a release moiety which is preferably resonance stabilized or a tertiary alkyl type and which acts to aid the nitrogen-containing species in functioning as a leaving group.

摘要:The invention discloses a method for producing a charge control agent and a toner containing the charge control agent. The preparation method includes the technical proposal that in aqueous medium, an azo compound is reacted with a salicylic acid chromium complex, which is used as a complexing agent to synthesize a specific azo chromium complex. The preparation method is characterized by complex synthesis engineering. The toner of the invention includes a charge control agent obtained from the method described herein. Provided is a method for obtaining a charge control agent and a toner with excellent chargeability in that no flying or fogging is observed, even during image formation at high printing speeds. The toner is relatively free from the influences of variations in the environmental temperature and humidity, which ensures stable image printing with high picture quality for long periods of time.
