Polyvinyl Alcohol and Polyvinyl Acetate

2020
Basically only ethylene and air are needed for the production of polyvinyl acetate (PVAc) and its polymer analogous products, such as polyvinyl alcohol and polyvinyl butyrate. Polyvinyl acetate serves as the precursor for polyvinyl alcohol and, directly or indirectly, the polyvinyl acetals.

Kinetics of acetalization of polyvinyl alcohol and of hydrolysis of acetalized polyvinyl alcohol

Die Makromolekulare Chemie, 1959
AbstractLa cinétique d'acétalisation de l'alcool polyvinylique au moyen d'acétaldéhyde a été étudiée en soulution dioxanne‐eau à différentes températures en présence d'acide sulfurique comme catalyseur.L'ordre de la réaction est unitaire par rapport à la concentration en acide et en acétaldéhyde.

Polyvinyl Alcohol

Reactions Weekly
Polyvinyl alcohol (PVA) is one of the main exploited Water-Soluble Polymers (WSPs), from packaging production to biomedical purposes. However, despite its widespread use, there still seems to be some controversy regarding its chemical safety. In this brief chapter the main knowledge in the PVA (eco)toxicological field is summarized, highlighting how ...

Polyvinyl alcohol and modified polyvinyl alcohol reverse osmosis membranes

Desalination, 1993
Abstract A study was conducted on the insolubilization of polyvinyl alcohol. Polyvinyl alcohol was regarded as a stable material for the formation of gel layer base membranes, which could then be further modified to produce RO membranes with good salt retention.

Polyvinyl alcohol and polyvinyl alcohol/ polyvinyl pyrrolidone biomedical foams crosslinked by gamma irradiation

Journal of Cellular Plastics, 2016
Foams for biomedical applications were made from polyvinyl alcohol, polyvinyl alcohol / polyvinyl pyrrolidone blend and their nanocomposites with nanoclay by clean processes. Air was entrapped into the aqueous polymer solutions during vigorous mixing and then the solutions were freeze-dried. The foams structure was stabilized by crosslinking via gamma

Acetalization of Polyvinyl Alcohol Fiber with Aldehyde-containing Polyvinyl Alcohol Fiber

Russian Journal of Applied Chemistry, 2001
A procedure is proposed for preparing polyvinyl alcohol fiber with increased water absorption by acetalization of a freshly formed fiber with dialdehyde-containing polyvinyl alcohol fiber. The fiber characteristics were determined in relation to the acetalization conditions.

Diethylphosphonacetals of polyvinyl alcohol

Polymer Science U.S.S.R., 1970
THE production of linear phosphorus-containing polymers of high mol.wt, is known to "be difficult [1]. Polymer-analogue reactions are quite promising for this purpose, but only where mild conditions are used, and where the reaction does not result in secondary products. These rquirements are met by the acetalation of polyvinyl alcohol (PVA).
