Polyvinylamine: A Tool for Engineering Interfaces | Langmuir
2014年6月25日 · Based on the free radical polymerization and subsequent hydrolysis of N-vinylformamide, PVAm is prepared as linear polymers (0.8 kDa to >1 MDa), microgels, macrogels, and copolymers. The amine groups serve as reaction sites for grafting PVAm to surfaces and for the preparation of derivatives.
Poly (vinyl amine) microparticles derived from - Springer
2021年9月3日 · Poly (vinyl amine) (PVAm) is a cationic polyelectrolyte containing the highest number of primary amine groups among any other polymers. Here, we introduce a general method in synthesizing PVAm microparticles via a surfactant-free water-in-oil emulsion technique using cyclohexane as the oil phase and aqueous PVAm solution as the dispersed phase.
Structural and water diffusion of poly (acryl amide)/poly (vinyl ...
The simulation results show that the diffusion coefficient of water molecules and fractional free volume (FFV) of blend membranes increase with the addition of PAM, and a higher temperature can also improve the diffusion of water molecules.
Poly(vinyl amide) and Poly(vinyl amine) Families - CD ... - CD …
Poly(vinylamide) polymers are characterized by the presence of amide bonds in the backbone and have significant biocompatibility and tunable physicochemical properties. These properties make them ideal candidates for encapsulating and releasing pharmaceutical agents in a controlled manner, thereby solving challenges related to drug stability ...
Structure of the Tables If available, molecular structure and CAS number are represented. The molecular structure of the polymer is related to the vibrational modes. Carbon and hydrogen atoms of an aromatic unit are mostly not indi-cated. Polymers or structural units of polymers that can have a para-, meta-, or ortho-arrangement are
Synthesis of Poly( N -vinylamide)s and Poly(vinylamine)s and Their ...
2019年3月28日 · Starting blocks: Structurally controlled poly(vinylamide)s and poly(vinylamine)s were synthesized by organotellurium-mediated polymerization (TERP) of acyclic vinylamides and subsequent hydrolysis of the amides. A block copolymer with a poly(vinylamine) segment was also synthesized.
Polyvinylamine | Formula, Properties & Application
Polyvinylamine is a synthetic polymer that is constituted by repeat units of vinylamine. The monomer, vinylamine, has a primary amine group (-NH 2) attached to a vinyl group, creating a structure that allows the polymer to be readily functionalized. This versatility is one of PVAm’s most defining characteristics.
Structural-property relationship in poly(vinyl aniline-co-maleic ...
2024年1月20日 · Adipic acid crosslinked poly (vinyl amine- co -maleic anhydride) synthesized and hydrolyzed to poly (vinyl amine- co -maleic acid). Both crosslinked polymers have target specific structural features suitable for use as Hg 2+ ions adsorbents. Adsorbents possess high selectivity and high adsorption capacity with good recyclability up to 10 cycles.
