Synthesis and characterization of copper (II)-poly (acrylic acid)/M-MCM-41 nanocomposite as a novel mesoporous solid acid catalyst for the one-pot synthesis of polyhydroquinoline derivatives Shahla Vaysipour, Z. Rafiee, M. NasrEsfahani Chemistry 2020 13 A polymer/mesoporous molecular sieve composite: Preparation, structure and properties When the polymer encounters water, the dissociation groups (-COONa+) immediately dissociate into positively charged low molecular ions (Na+) and negatively charged high molecular ions. People use polyacrylate sodium as scale inhibition and dispersant. Can be crosslinked covalently or ionically to form hydrogels. Such as waste control, drilling fluid, corrosion inhibitor, concrete protection, etc. PAA 450K is an important anionic water-soluble polymer. Low non-specific binding supports and formulations for performing solid-phase nucleic acid hybridization and amplification are described that provide improved performance for nucleic acid detection, amplification, and sequencing applications.
