Preparation of Hydrophobic Association Polyacrylamide in a New Micellar Copolymerization System and Its Hydrophobically Associative Property Gao, Baojiao Guo, Haopeng
The hydrophobic associating polyacrylamide prepared with aqueous two-phase polymerization exhibited superior solubility and it could dissolve completely in twenty seconds. HAPAM solution could aggregate to network through inter-molecular association, leading significant increase of viscosity.

The micellar copolymerization, therefore, resulted in a ternary hydrophobic association polyacrylamide (HAPAM), namely, C 12 AM/NaAMC 12 S/AM or DiC 12 AM/ NaAMC 12 S/AM. The chemical structures of these ternary copolymers were characterized with Fourier transform infrared (FTIR) spectroscopy, and their hydrophobic associative behavior as well

In coal preparation plant circuits, fine coal particles are aggregated either by oil agglomeration or by flocculation. In a new hydrophobic agglomeration process, recently developed hydrophobic latices are utilized. While the selectivity of such aggregation processes determines the beneficiation results, the degree of aggregation has a strong effect on fine coal filtration. The aim of this

Recent studies revealed higher polymer flooding performance upon adding metal oxide nanoparticles (NPs) to acrylamide-based polymers during heavy oil recovery. The current study considers the effect of TiO2, Al2O3, in-situ prepared Fe(OH)3 and surface-modified SiO2 NPs on the performance of xanthan gum (XG) solutions to enhance heavy oil recovery. Surface modification of the SiO2 NPs was
Acrylamide is a colorless, odorless, crystalline amide that polymerizes rapidly and can form as a byproduct during the heating of starch-rich foods to high temperatures.Acrylamide is used in the production of polymers mainly in the water treatment industry, pulp and paper industry and textile treatment industry and is used as a laboratory reagent. . The polymer is nontoxic, but exposure to the
Effect of Network Parameters of Preformed Particle Gel
Summary. Preformed particle gel (PPG) is an appropriate solution for conformance control and water management in low permeability reservoirs. In this paper, the network parameters of PPGs are evaluated through swelling tests and rheology and by determining their role in maintaining structural strength.
Surfactant-grafted Polyacrylamide (S-PAM), as a new type of oil displacement agent in oilfield, integrates the advantages of both polymer and surfactant. The oil displacement experiments using S-PAM in multi-blocks reveal that in-use S-PAMs differ greatly from ordinary polymers and the physical properties remain unclear. This is unfavorable to production application and occupational health and
- Where are polyacrylamides used in New Zealand?
- 1.6.3 Most polyacrylamides used in New Zealand for drinking-water treatment are manufactured in the USA, Europe and Australia. Polyacrylamides are normally dosed directly to water from a mixing or day tank via a positive displacement metering pump.
- What is anionic polyacrylamide?
- Anionic Polyacrylamide, is solid powder water-soluble polymer with varying molecular weight and charge density. It is most often used to increase the viscosity of water (creating a thicker solution) or to encourage flocculation of particles present in water and allow rapid settlement of finely suspended solids.
- Does anionic polyacrylamide biodegrade?
- ent only.1 BACKGROUNDAnionic polyacrylamide is the copolymer of acryl mide and acrylic acid. No studies on the environmental fate of polyac ylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biode rade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concer
