Solubility Study of Polyacrylamide in Polar Solvents - CORE
Abstract. Contact angles and surface tension data were measured to obtain the surface tension components of polyacrylamide (PAM). According to Van Oss, Chaudhury, and Good (VCG) theory, the surface tension components were used to calculate the PAM solubility in five different polar solvents: water, ethylene glycol (EG), acetone, ethanol, and dimethyl formamide (DMF).

The Solubility of Polyacrylonitrile
The comparative study of the thermodynamic solubility of PAN in five solvents led to the following conclusions: the thermodynamic solubility of PAN, characterized by the experimental and calculated cloud point curves, differ significantly for two kinds of solvents: organic aprotic and inorganic aqueous solution of NaSCN; the solubility of PAN in an aqueous solution of NaSCN is much higher than
The study of nucleic acids in low-polarity environments paves the way for novel biotechnological applications of DNA. Here, we use a repertoire of atomistic molecular simulation tools to study the nature of DNA when placed in a highly apolar environment and when transferred from aqueous to apolar solvent. Our results show that DNA becomes stiffer in apolar solvents and suggest that highly
Predicting Cosolvency. 1. Solubility Ratio and Solute log
The solubility ratio of organic chemicals in an organic solvent and in water, σ, has been found to correlate with the logarithm of the octanol−water partition coefficient (log Kow) of the solutes; i.e., log σ = N + M log Kow. A total of 607 sets of thousands of solubility data were extracted from literature sources. From this database, values of N and M are obtained for 15 completely water
Advances in polymer science have led to the development of novel drug delivery systems. Some polymers are obtained from natural resources and then chemically modified for various applications, while others are chemically synthesized and used. A large number of natural and synthetic polymers are available. In the present paper, only water soluble polymers are described.
Application of hydrophobically modified water‐soluble
In polar solvents, these molecules may associate into micelle‐like structures with hydrophobes as the core while the hydrophiles extend into the corona phase, and vice versa for the nonpolar solvents. 33 This behavior implicates that PAAm‐g‐PEO‐PPO copolymer surfactant tends to the micelle formation, and also the micelle inversion
The vast majority of industrial chemical synthesis occurs in organic solution. Solute concentration and solvent recovery consume ~50% of the energy required to produce chemicals and pose problems that are as relevant as the synthesis process itself. Separation and purification processes often involve a phase change and, as such, they are highly energy-intensive.
Synthesis and Characterization of Poly(styrene-co
Electrospun nanofibers present a new and rapidly growing research area due to their pronounced micro and nano characteristics associated with high surface area to volume ratio. Poly(styrene-co-acrylamide) and polystyrene polymers were synthesized by boiling temperature soap free emulsion polymerization in aqueous medium with potassium peroxosulphate as the initiator.
Polyacrylamide (PA) crosslinked with four different crosslinking agents, triethyleneglycol dimethacrylate (TEGDMA), N,N′‐methylene bisacrylamide (NNMBA), hexanediol dimethacrylate (HDDMA) and divinylbenzene (DVB), with mole percents ranging from 5 to 20, was prepared by solution polymerization and subjected to swelling and solvation studies. Solubility parameters and cohesive energy
- What is nonionic polyacrylamide (NPAM) gel?
- Nonionic polyacrylamide (NPAM) gel was prepared for in-depth profile control. A compact three dimensional network structure was formed in the bulk gel system. Retention, adsorption and bridging across the pore throats occur in high permeability zones. The NPAM gel shows superior high temperature resistant. °C.

- Conclusions In this work, a phenolic resin cross-linked NPAM gel was selected as an in-depth profile control agent for water production control. The gelation time and gel strength of the NPAM gel can be controlled by adjusting the NAPM polymer or cross-linker concentration.
- Can nonionic polyacrylamide be used as a gel fracturing fluid?
- Nonionic polyacrylamide (NPAM) with controlled molecular weight was successfully synthesized as a gel fracturing fluid by aqueous solution polymerization.
- What is an anionic polyacrylamide?
- Anionic polyacrylamides make up the largest portion of the polyacrylamide market. The polymers can be prepared over a wide range of anionic charges and molecular weights (1000 to > 20,000,000 molecular weight). The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid.
