Microwave initiated synthesis of polyacrylamide grafted
2.2. Microwave initiated synthesis of polyacrylamide grafted guar gum (GG-g-PAM) In this method, microwave irradiation alone was used to generate the free radical sites on the polymer backbone. No free radical initiator was used in the process. The details of the method of synthesis as employed were as followed.

Polyacrylamide
Polyacrylamide (abbreviated as PAM) is a polymer with the formula (-CH2CHCONH2-). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for

White Cationic Polyacrylamide Emulsion , High Molecular
Our Cationic polyacrylamide Emulsion EC-8040 grade (CPAM) is a water based polymer. Anionic Polyacrylamide has a big range of high molecular weight from 6-12 million, with an anionic charge density ranging from 10-60%. EC-8040 grade has high molecular weight, and medium to high charge degree.
Polyacrylamide (PAM) Application Water treatment: The application of PAM in the water treatment industry mainly includes three aspects: raw water treatment, sewage treatment and industrial water treatment. In raw water treatment, PAM can be used
- What is anionic polyacrylamide (Apam)?
- 1. Introduction Anionic polyacrylamide (APAM) is a kind of organic high-molecular polymer with high hydrophilicity and viscosity, which is easily dissolved in water [ , , ].
- What is a polyacrylamide (PAM)?
- 1. Introduction Polyacrylamides (PAM) are high molecular weight polymers deriving from the polymerization of acrylamide monomers. Their chemical composition and ionic character depend on the functional groups added to the acrylamide chemical moiety ( Abidin et al., 2012; Acharya et al., 2010 ).
- Is Apam a uniform polymer?
- The polyacrylamide is a uniform and unitary polymer. PAM has a neat smooth surface as its SEM images unfold at 2500x and 4000x. However, the surface of APAM was much rougher. Hills and valleys could be observed in its SEM images due to the interaction of chemical groups between AM and SAS.
- What is Apam chemistry?
- The APAM samples were supplied in powder form by SNF (France). They had a low charge density, low to medium molecular size, and identical chemistry to APAM intended for industrial use. Three different molecular weights of the same polymer type were used in this study featuring average molecular weights of 200, 2800 and 8000 kDa, respectively.
