Ultraviolet (UV)-initiated template polymerization (UTP) was used as a feasible strategy to prepare a novel anionic polyacrylamide (APAM) with a microblock structure. In the template copolymerization system, acrylamide (AM) and sodium allylsulfonate (SAS) were used as monomers, and poly (allylammonium chloride) (PAAC) as a template.

polyacrylamide

Polyacrylamide

Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). 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 water treatment and the paper and mineral industries. [1] Physicochemical properties [ edit]

Acute and long-term effects of anionic polyacrylamide (APAM) on different developmental stages of two marine copepod species

Hatching time, hatching success and nauplii survival was determined in very early life stages (eggs to NI/NII) of copepods following APAM exposure (200 kDa, 2800 kDa and 8000 kDa, respectively). The average time from shedding of eggs to 50% hatching for all C. finmarchicus groups (n = 163) was 29.4 ¡À 1.1 h (Fig. 2 A ¨C C), with no significant differences between the control groups and

Evaluation a self-assembled anionic polyacrylamide flocculant for the treatment of hematite wastewater: Role of microblock structure

Anionic polyacrylamide (APAM) as an important flocculant possess the advantages of high molecular weight, acceptable flocculation performance, low cost and green [4]. The anionic chemical groups in APAM are able to neutralize the positive charge of colloid particles in the wastewater and lead them to crash, aggregate and settle.
