Current status on the biodegradability of acrylic polymers: microorganisms, enzymes and metabolic pathways involved
Abstract Acrylic polymers (AP) are a diverse group of materials with broad applications, frequent use, and increasing demand. Some of the most used AP are polyacrylamide, polyacrylic acid, polymethyl methacrylates, and polyacrylonitrile.

Acrylamide in Drinking-water - WHO
Acrylamide is highly mobile in aqueous environments and readily leachable in soil. As it has a higher mobility and lower rate of degradation in sandy soils than in clay soils (Lande et al., 1979), it may contaminate groundwater. However, its
The polyacrylamide gel electrophoresis was used for determining the Griseofulvin degrading enzyme purity, together with retention factor (R f) and molecular masses (Mr). The biodegradation product of Griseofulvin is identified by using Gas Key

To achieve high output rates, an appropriate extruder screw design has to be selected. Major manufacturers of extrusion equipment provide special screws, e.g., for PLA and PLA compounds. Because of the incompatibility of most standard polymers
Soil microcosm experiments examining biodegradation rates of cross-linked PAM copolymer indicated degradation rates as high as 7% per 80 days. Chang et al. [ 7 ] examined the aerobic and anaerobic biodegradation of cationic-PAM and showed the

Fe³⁺ and Zn²⁺ significantly enhanced PN and PS secretion, which may have promoted CB adsorption and biodegradation. High-throughput sequencing revealed the promoting effect of Fe³⁺ and
The aim of this study was to design a probe that enables determination of the main biodegradation compartments of a recombinant protein. Recombinant human butyrylcholinesterase, a bioscavenger of organophosphorus agents, was used as an example

Polyacrylamide (PAM), a linear water sol. polymeric compd. with high mol. wt., is extensively used for oil prodn. in Cooking. Compared with the physico-chem. degrdn. of PAM, there is no acrylamide monomer, which causes peripheral neuropathy,
We believe that biodegradability is a key property of materials used to provide better solutions to the design of 3D tissue constructs and drug delivery systems. Better understanding of the biodegradation process will allow us to design advanced
- Why is anionic polyacrylamide chosen?
- Anionic polyacrylamide is chosen because the intramolecular electrostatic repulsion between polymer segments forces the polymer chains to adopt a more extended conformation, increasing the efficiency of bridging flocculation.
- Can anionic polyacrylamide be used in water treatment?
- What's more, the authors discussed the application status of anionic polyacrylamide in water treatment. Based on these reviews, future research perspectives relating to its synthesis and application were proposed. This review summarizes the synthesis methods for anionic polyacrylamide.
- What are the different types of anionic polyacrylamide synthesis technologies?
- The paper lists six different kinds of anionic polyacrylamide synthesis technologies, including homopolymerization posthydrolysis process, homopolymerization cohydrolysis process, copolymerization approach, inverse emulsion polymerization, precipitation polymerization and radiation polymerization.
- How is an anionic polyacrylamide flocculant synthesized?
- In this study, an anionic polyacrylamide flocculant was synthesized by ultrasonic initiated template copolymerization (USTP), using sodium allylsulfonate (SAS) and acrylamide (AM) as monomers, poly diallyl dimethyl ammonium chloride (polyDADMAC) as template, and 2,2′-azobis [2- (2-imidazolin-2-yl) propane] dihydrochloride (VA-044) as initiator.
