What is high relative molecular weight polyacrylamide used for?

Ultra high relative molecular weight polyacrylamide is mainly used for three oil recovery in the oil field, high relative molecular weight polyacrylamide is mainly used as flocculant, medium relative molecular weight polyacrylamide is mainly used as paper dry strength agent, low relative molecular weight polyacrylamide is mainly used as dispersant.

How are high molecular weight polyacrylamide nanoparticles prepared?

High molecular weight polyacrylamide nanoparticles were prepared by inverse-emulsion polymerization of aqueous acrylamide solution in xylene as a continuous phase under various conditions in the presence of a mixture of non-ionic emulsifiers (Tween 85 and Span 80).

What is P olyacrylamide (Pam) & its copolymers?

P olyacrylamide (PAM) and its copolymers are of important polymeric materials in petroleum industry, for example in drilling fluids and enhanced oil recovery. High molecular weights of these polymers are needed to have optimum efficiency in the above given applications.

Which polymer is used to produce partially hydrolyzed polyacrylamide (HPAM)?

PAM is used to produce partially hydrolyzed polyacrylamide (HPAM), which is linear, anionic, water-soluble, stable, polymeric, and high molecular weight chain of acrylamide (C 3 H 5 NO) monomers (Bao et al., 2010; Braun et al., 2022; Liu et al., 2016; Xiong et al., 2018).

What is polyacrylamide (PAM)?

Polyacrylamide (PAM) is acrylamide monomer under the action of initiator homopolymerization or copolymerization of polymers, is one of the most widely used water-soluble polymer materials, mainly used in oil exploitation, water treatment, textile, paper making, mineral processing, medicine, agriculture and other industries. PAM product category:

Is polyacrylamide soluble in water?

Polyacrylamide (PAM) is a synthetic polymer of long-chain acrylamide subunits, high molecular weight (1000 to 20 × 10 6 g/mol), and a wide range degree of hydrolysis (Abidin et al., 2012; Joshi & Abed, 2017). It is extremely soluble in water, but not soluble in organic solvents, such as methanol and hydrocarbons (Lu & Wu, 2002; Braun et al., 2022).
