Gao C, Wang S, Dong X, Liu K, Zhao X, Kong F. Construction of a Novel Lignin-Based Quaternary Ammonium Material with Excellent Corrosion Resistant Behavior and Its Application for Corrosion Protection. Materials (Basel). 2019 May 31;12(11):1776. doi: 10.3390/ma12111776. 

Abstract. A novel lignin-based quaternary ammonium material (lignin-DMC) with excellent corrosion resistant behavior was synthesized by grafting DMC (methacrylatoethyl trimethyl ammonium chloride) onto kraft lignin. The structure and anti-corrosion performance of lignin-DMC was investigated using many methods, for instance the scanning electron microscope (SEM), atomic force microscopy (AFM), charge density analysis, molecular weight analysis, electrochemical methods.

Abstract. In this study, a natural polymer-based organic flocculant (sodium alginate-methacrylatoethyl trimethyl ammonium chloride, SA-PDMC) was synthesized by graft copolymerization. The optimum preparation procedures were determined by single factor experiments.

Abstract. Xylan sulfate, one important xylan derivative, was prepared using microfluidic reactor system and incorporated in situ under the polymerization of methacroylcholine chloride (DMC), resulting in composite hydrogels containing variable amount of xylan sulfate.

Tan X, Duan L, Han W, Li Y, Guo M. A Zwitterionic Copolymer as Rheology Modifier and Fluid Loss Agents for Water-Based Drilling Fluids. Polymers (Basel). 2021 Sep 16;13(18):3120. doi: 10.3390/polym13183120.

Abstract. To overcome the negative impact on the rheological and filtration loss properties of drilling fluids caused by elevated temperature and salts contamination, which are common in ultradeep or geothermal drilling operations, it is imperative to develop highly efficient additives used in the water-based drilling fluid. In this study, a zwitterionic copolymer P (AM/DMC/AMPS/DMAM, ADAD) was synthesized by using acrylamide (AM), cationic monomer methacrylatoethyl trimethyl ammonium chloride (DMC), anionic monomer 2-acrylamide-2-methyl propane sulfonic acid (AMPS), and N,N-dimethylacrylamide (DMAM) through free radical copolymerization.

Abstract. To achieve high water flux, the majority of positively charged NF membranes consist of a thin active skin deposited on a thick, permeable support, while the connection force between the active layer and the support is a physical force which may cause the membrane unstable in the long running. In general, chemical bond connection may show superior stability.

Abstract. A hydrophilic monolithic CEC column was prepared by thermal copolymerization of zwitterionic monomer 2-methacryloyloxyethyl phosphorylcholine (MPC), pentaerythritol triacrylate (PETA), either methacrylatoethyl trimethyl ammonium chloride (META) or sodium 2-methylpropene-1-sulfonate (MPS) in a polar binary porogen consisting of methanol and THF.

Abstract. A hyper-cross-linked polymer monolithic column, poly(methacrylatoethyl trimethyl ammonium-co-vinylbenzene chloride-co-divinylbenzene) (MATE-co-VBC-co-DVB) with phenyl and quaternary ammonium groups was successfully prepared in the current study.
