Study on Branched Polyacrylamide Preparation and Application

Preparation and application of polyacrylamide via aqueous copolymerization was studied as dry strength agent in this paper. The polyacrylamide with middle molecular weight and low viscosity was obtained by reacting acrylamide, cationic monomer [2- (acryloyloxy)ethy] -trimethylammonium chloride and N,N-dimethylaminoethyl methacrylate, anionic

Synthesis and applications of quaternized highly branched

In current study, quaternized highly branched polyacrylamide (HBAA) was synthesized and used as an efficient multi-site polymeric phase transfer catalyst in nucleophilic substitution reactions and also in synthesis of α, β-unsaturated nitriles from reaction of acetonitrile and carbonyl compounds. The quaternized HBAA was synthesized via two steps. First, HBAA was synthesized via self

Study on Properties of Branched Hydrophobically Modified

In order to improve traditional polyacrylamide’s properties and its applications in high temperature and salinity reservoirs, HPAM should be modified to change the viscosifying way. In this paper, we synthesized a new branched hydrophobically modified polyacrylamide (BHMPAM) and evaluated the properties of the polymer solution. 2.
