effects of physicochemical properties of polyacrylamide (paa)

Effects of physicochemical properties of polyacrylamide (PAA)

To prepare a PAA network structure, the initiator is used as a source of chemical species that reacts with a monomer to create an intermediate compound able to link successively with other monomers. 56 The type of initiator has a profound effect on the polymer product. When initiator concentration is increased, the number of active sites available to react with monomers also increases.

polyacrylamide

Polyacrylamide

Polyacrylamide (PAA) Polyacrylamides are water-soluble synthetic linear polymers made of acrylamide or the combination of acrylamide and acrylic acid. Polyacrylamide finds applications in pulp and paper production, agriculture, food processing, mining, and as a flocculant in wastewater treatment. Polyacrylamide undergoes thermal degradation at

rapid raft polymerization of acrylamide with high conversion

Rapid RAFT Polymerization of Acrylamide with High Conversion

This study shows that ideal Reversible Addition¨CFragmentation Chain Transfer (RAFT) polymerization of acrylamide is achieved in dimethyl sulfoxide (DMSO) solution at 70 ¡ãC. The key to success is the appropriate choice of both a suitable RAFT chain transfer agent (CTA) and initiating species.

polyacrylamide

Polyacrylamide

Polyacrylamide. Polyacrylamide (PAM) is a commercially relevant cationic polymer utilized mainly for water treatment due to its high efficiency and rapid dissolution. Being a cationic polymer, PAM can increase the settling rate of bacterial floc and improve the capture of dispersed bacterial cells, suspended solids, and cell fragments

Surfactant Self-Assembling and Critical Micelle Concentration: One

Critical micelle concentration (CMC) is the main chemical¨Cphysical parameter to be determined for pure surfactants for their characterization in terms of surface activity and self-assembled aggregation. The CMC values can be calculated from different techniques (e.g., tensiometry, conductivity, fluorescence spectroscopy), able to follow the variation of a physical property with surfactant
