What are the optical properties of polyacrylamide (PAM) solution?

The optical properties of polyacrylamide (PAM) solution play an important role in measuring PAM concentration of the solution in the polymer flooding of oilfield based on optical methods.

What is the refractive index of Pam solution?

The refractive index of PAM solution increases with the increase of temperature, and the values of refractive index of PAM solution are in the range of 1.32–1.38. 1. Introduction

How are refractive index increments of polyacrylamide determined?

The refractive index increments of polyacrylamide for various wavelength were determined both in the usual solvents (water, ethylene glycol, formamide) and in those so far unused (ethanolamine, dimethyl sulfoxide). The values thus obtained are compared with the reported data. The necessity to employ anhydrous polyacrylamide samples is stressed.

Why is polyacrylamide a polar polymer?

Introduction As a linear polymer, polyacrylamide (PAM) has the amide group with high polar in its molecular structure, which results that it has the characteristics of hydrogen bonding and high reactivity. PAM solution is used in a very wide range of oil exploitation, sewage treatment and paper making , , , .

Is polyacrylamide soluble in organic solvent?

rmula: C3H5NOMolecular weight: 71.0079Description: Polyacrylamide, kno n as PAM, is a white powder or granule. Polyacryla ide is a kind of macromolecule polymer. It s not soluble in some organic solvents. Provided with a good flocculability, Polyacrylamide can lower

What is polyacrylamide (PAM)?

Polyacrylamide (PAM) is a macromolecular polymer, and its solution is widely applied in oil exploitation, sewage treatment and paper making.
