Traceable polymer and preparation method and application thereof

Abstract

The invention relates to a traceable polymer and a preparation method and application thereof. By adopting an emulsion polymerization method, water taken as a solvent, lauryl sodium sulfate used as an emulsifier, an ammonium persulfate and tetramethylethylenediamine redox system taken as an initiator, and 8-(4- benzyloxy-vinyl)-1,3,6-pyrene trisulfonic acid trisodium taken as a fluorescent tracer copolymerize with monomers acrylamide and 2-acrylamide-2-methyl propane sulfonic acid under certain temperature and pH conditions, so as to obtain the traceable polymer. The synthetic reaction is carried out under mild conditions, raw materials are easily available, the cost is low, the monomer conversion rate is high, products are easily processed, and the obtained traceable polymer can be applied to accurate determination of the concentration of the polymer, and a metal ion detector and has great potential application value in chemical analysis.

Description

technical field [0001] The invention relates to a traceable polymer and its preparation method and application. The polymer can effectively detect the polymer concentration and detect metal ions, and belongs to the technical field of water-soluble polymer synthesis. Background technique [0002] The determination of chemical substance composition has long been a difficult problem in the chemical industry, especially for high molecular polymers, it is difficult to determine the content of components in an unknown solution. Generally speaking, the methods for determining the concentration of polymers include turbidimetry, starch-iodine Cadmium method, viscosity method, gel chromatography, Kjeldah nitrogen method, precipitation method, etc. Among these methods, the turbidity method, the Kjeldah nitrogen determination method and the starch-cadmium iodide method are greatly affected by the solution environment, and it is difficult to perform accurate measurements; the viscosity m...

Problems solved by technology

Among these methods, the turbidity method, the Kjeldah nitrogen determination method and the starch-cadmium iodide method are greatly affected by the solution environment, and it is difficult to perform accurate measurements; the viscosity method is greatly affected by the viscosity temperature, pH and other conditions, and it is generally difficult to obtain accurate values; Gel chromatography requires extremely high sample purity, and extremely damages the chromatographic column, resulting in high detection costs, which seriously limits its large-scale application; the precipitation method will cause polymer loss during the polymer precipitation process, greatly reducing its accuracy

Since these methods are measured by methods other than the polymer itself, it is difficult to accurately obtain target data
