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...

Evaluation of morphology and cell behaviour of a novel synthesized electrospun poly(vinyl pyrrolidone)/poly(vinyl alcohol)/hydroxyapatite nanofibers

Objective(s): Three-dimensional structures such as nanofibrous scaffolds are being used in biomedical engineering as well as provide a site for cells to attach and proliferate leading to tissue formation. In the present study, poly(vinyl pyrrolidone) (PVP)/ poly(vinyl alcohol)(PVA) hybrid nanofibrous scaffold was synthesized by electrospinning. Materials and Methods: The effect of adding nano h...

Effects of Nanoclay on Cellular Morphology and Water Absorption Capacity of Poly(vinyl alcohol) Foam

The present work was aimed to examine the effects of incorporation of each of two different types of nanoclay, i.e. Cloisite Na+ and Cloisite 30B, into PVA foam on cellular morphology and water absorption capacity. Foam samples containing 0.0-10.0 wt% of each of the two types of nanoclay alone were prepared using mechanical foaming. Accordingly, PVA/organoclay/water suspensions were prepare...

Intramolecular crosslinking of poly(vinyl alcohol)

Poly(vinyl alcohol) is crosslinked in dilute solution (c = 0.1 wt%) with glutaraldehyde. The reaction product is characterized by viscometry and gel permeation chromatography (g.p.c.). The intrinsic viscosity decreases with increasing degree of crosslinking and does not depend on temperature. G.p.c. reveals that the reaction product is not homogeneous, but consists of a mixture of particles wit...

The Plasticizing Mechanism and Effect of Aluminium Chloride and Glycerin on Poly(vinyl alcohol) Films

Poly(Vinyl Alcohol) (PVA) films were prepared with AlCl3·6H2O/glycerin and AlCl3·6H2O/poly glycerin as two kinds of complex plasticizer. The micromorphology of pure PVA film and PVA films plasticized with complex plasticizer was observed by Scanning Electron Microscope (SEM). The interaction between complex plas...
