At present, there are no literature reports on the synthetic process route, preparation method and antistatic performance of polymers containing quaternary ammonium salts, tertiary ammonium salts and tertiary amines in the main chain.

Description

technical field [0001] The invention relates to a preparation method of a polymer solution containing quaternary ammonium salt, tertiary ammonium salt and tertiary amine on the main chain, and belongs to the technical field of polymer preparation. Background technique [0002] With the rapid development of organic polymer materials, the application of organic polymer materials is becoming more and more extensive, playing an increasingly important role in the national economy. However, since most of the organic polymer materials have excellent insulating properties, the organic polymer materials are likely to generate static electricity accumulation on the surface of the organic polymer materials through mutual collision, mutual friction or electrostatic induction during use, and static electricity is difficult to The electrostatic voltage is continuously increased through conduction elimination. Excessive static electricity is not only easy to absorb dust, but also easy to g...
