A study on the synthesis and application of an inverse emulsion of amphoteric polyacrylamide as a retention aid in papermaking
In this study, we successfully prepared a polyacrylamide (PAM) water-in-water (W/W) emulsion through dispersion polymerization with only a small concentration of gelatin as the stabilizer.
Abstract A water soluble branched cationic polyacrylamide (BCPAM) was synthesized using solution polymerization. The polymerization was initiated using potassium diperiodatocuprate, K 5 [Cu(HIO 6) 2](Cu(III)), initiating the self-condensing
Preparation of amphoteric polyacrylamide flocculant and its application in the treatment of tannery wastewater - Zhu - 2011 - Journal of Applied
Through two‐phase aqueous polymerization, amphoteric polyacrylamide (AmPAM) emulsion, as an environmental friendly flocculant for the tannery wastewater, was firstly synthesized using ammonium sulfate aqueous solution as the dispersion, using
Swelling properties of amphoteric polyacrylamide (AmPAM) dispersions were investigated by measurements of apparent viscosity and particle morphology. AmPAM dispersion was prepared by dispersion polymerization in aqueous solution of ammonium
Effect of hydrophobic monomer on the aqueous dispersion polymerization of acrylamide with quaternary ammonium cationic monomer
Aqueous dispersion polymerization has been considered as a promising green technology for preparing water-soluble polymers such as cationic polyacrylamide (CPAM). Dispersion copolymerization of acrylamide and 2-methylacryloylxyethyl trimethyl
Polyacrylamide emulsion is a new polymer material made of acrylamide through special process polymerization since 1960s. The polyacrylamide emulsion is by a polymerization reaction in which a water-soluble monomer (acrylamide) is dissolved in an
Photoinitiated Polymerization of Cationic Acrylamide in Aqueous Solution: Synthesis, Characterization, and Sludge Dewatering Performance
A copolymer of acrylamide (AM) with acryloyloxyethyl trimethyl ammonium chloride (DAC) as the cationic monomer was synthesized under the irradiation of high-pressure mercury lamp with 2,2-azobis(2-amidinopropane) dihydrochloride (V-50) as the
A polymerization process prepares a water-soluble polymer in the form of a water-continuous dispersion. In this process the peak in-production viscosity developed in the aqueous reaction mixture is lower than the peak in-production viscosity
- What is cationic polyacrylamide (CPAM)?
- J. Pharm. Biopharm.54 (2002) 41–50. 10.1016/S0939-6411 (02)00036-X Search in Google Scholar Cationic polyacrylamide (CPAM) was prepared in aqueous solution by free radical polymerization of methacryloyloxy ethyl trimethylammonium chloride (DMC) and acrylamide (AM). A redox initiator system was used.
- What is copper-catalyzed controlled polymerization of acrylamide?
- Copper-catalyzed controlled polymerization of acrylamide (AM) has always been a challenge, which typically exhibits low monomer conversion and broad molecular weight distribution (MWD) or requires complex/multistep reaction procedures, due to the highly active nature of the AM radical and its side reactions.
- Which redox system is used for polymerization of acrylamide?
- Mechanism of polymerization of acrylamide using Ce 4+ /VA-086 redox system. To achieve significant degradation of the polymer, the insertion of multiple main-chain degradable functionalities is mandatory. Radical ring-opening polymerization (r-ROP) of cyclic monomers remains the process of choice to achieve this goal [186, 190, 191, 192, 193, 194].
- Does cationic polyacrylamide flocculate Phaeodactylum tricornutum?
- However, Nguyen et al., observed high flocculation efficiency of marine microalgae Phaeodactylum tricornutum with a cationic polyacrylamide flocculant (FO3801). The discrepancy in the literature suggested that a future flocculation study using one type of polymer with multiple marine species.
