Polyacrylamide because it in oil exploitation, water treatment, papermaking, medicine, textile, printing and dyeing, processing and other areas of the national economy has a wide range of uses, the "auxiliary industries," said. But now in the application of a large number of polyacrylamide, because of polyacrylamide and its derivatives in side of amide groups has hydrophilic, under certain conditions, easy to be hydrolyzed to carboxylic acid groups, using process exists obvious deficiency.

Mainly in salt tolerance, temperature difference, due to the shearing effect or chemical reaction easy degradation, sedimentation, with time and temperature changing is easy to hydrolysis or to hydration, viscosity of more and more small, reduce use efficiency. In order to overcome the above disadvantages, in recent years scientists is working on a variety of ways and means, of polyacrylamide modified, to meet the requirements of the applications in the field of high performance. In addition, various applications of polyacrylamide molecular weight also put forward increasingly high demand, increased by usual millions to tens of millions. Such a request not only challenges the traditional methods of polyacrylamide production, but also increases the cost of production.Therefore, it is a very concerned topic in this field that how to develop new water-soluble polymer to meet the above requirements.. The hydrophobic association water soluble polymer is a water-soluble polymer which is introduced into hydrophilic macromolecular chains of polymer.

In the polymer solution, hydrophobic groups occur aggregation due to hydrophobic interaction, which makes the macromolecular chain molecules and intermolecular association. The formation of this hydrophobic structure, so that the polymer solution is a unique solution, for the high viscosity and the special response to the shear, can adjust the fluid viscosity, rheological properties, etc.. So that it has a wide range of outstanding application prospect in the three oil recovery, paint, paper, water treatment, medicine and other industries, and thus got the attention of researchers in various countries..

There are also many studies and some of the different uses of the hydrophobic association polyacrylamide invention patents, but its raw materials synthesis complex and expensive, so its application and industrialization is difficult. This research project with wide sources of raw materials, chemical products, simple and feasible synthetic process conditions and easy industrialized production method, synthesis of a novel hydrophobically associating polyacrylamide monomer and preparation of new hydrophobic associating polyacrylamide. To meet the high performance requirements of the application in various fields.The hydrophobic association water soluble polymer is a water-soluble polymer which is introduced into hydrophilic macromolecular chains of polymer.

In the polymer solution, hydrophobic groups occur aggregation due to hydrophobic interaction, which makes the macromolecular chain molecules and intermolecular association. The formation of this hydrophobic structure, so that the polymer solution showed unique solution properties, such as high viscosity and the special response to shear, can adjust the fluid viscosity, rheological properties, etc.. In the oil field three oil recovery, paint, paper, water treatment, medicine and other industries have a wide range of outstanding application prospects, and thus got the attention of researchers in various countries.
