Study on the Properties of Bicopolymer P (DMC-AM) solution

A cationic copolymer P(DMC-AM)is synthesized,and its structure is confirmed by IR spectrogram and 1H NMR spectrogram;a method of viscosity is used to study the basic properties of polymer,conclusions are drawn as follows:the basic viscosity of polymer solution decreases first and then increases.The intrinsic viscosity of polymer solution first increased,and then decreases with the increase of polymer concentration,the model for effect of salt concentration on solution viscometrics is also proposed.The reduced viscosity rises slightly with the increase of cation radius,but it's contrary to anion.The synthesized polymer is stable in acid solution,but it's easy to degrade in alkaline environment,The DMC monomer in the copolymer greatly enhances its resistance to high temperature;it has good flocculating capability for the bentonite simulated sewage with pH value from 4 to 9,and can delay the reaction velocity of acid with rock effectively.
