Poly(acrylic acid)–Poly(vinyl alcohol) Copolymers with Superabsorbent Properties
Biodegradable polyacrylates were produced by a series of novel copolymerization and/or crosslinking techniques using poly(vinyl alcohol) (PVA) moieties modified by the incorporation of olefinic structures. PVA was modified by a tosylation and/or detosylation reaction. The functionalized PVA was copolymerized and/or crosslinked with acrylic acid or its partially neutralized form to give crosslin...
متن کاملSynthesis of pH Sensitive Hydrogels Based on Poly Vinyl Alcohol and Poly Acrylic Acid
In this research, hydrogels based on poly vinyl alcohol and poly acrylic acid blend were prepared which were cross-linked by applied thermal conditions. Afterward, effects of time and heating on water uptake were investigated. The highest water uptake value exhibited by the sample that was heated for 20 min. at 110 ºC was about 2129% after 4 days at equilibrium state. Hydrogels exhibited p...
متن کاملSeparator Membrane from Crosslinked Poly(Vinyl Alcohol) and Poly(Methyl Vinyl Ether-alt-Maleic Anhydride)
In this work, we report separator membranes from crosslinking of two polymers, such as poly vinyl alcohol (PVA) with an ionic polymer poly(methyl vinyl ether-alt-maleic anhydride) (PMVE-MA). Such interpolymer-networked systems were extensively used for biomedical and desalination applications but they were not examined for their potential use as membranes or separators for batteries. Therefore,...

متن کاملDrug diffusion and binding in ionizable interpenetrating networks from poly(vinyl alcohol) and poly(acrylic acid).
Hydrogels of poly(vinyl alcohol) (PVA), poly(acrylic acid) (PAA), and their interpenetrating networks (IPNs) were prepared using glutaraldehyde and ethylene glycol dimethacrylate as crosslinking agents. The hydrogels were characterized by measuring their equilibrium polymer volume fraction, equilibrium swelling ratio, and mesh size. Drug and protein diffusion through these hydrogels were studie...
