Characterization of Hydrogen Bonding in Cellulose-Synthetic Polymer Blend Systems with Regioselectively Substituted Methylcellulose
TLDR
In this article, substituted O-methylcelluloaea, 2,3-di-O-methyl-cellulose and 6-O methylcelluloae were used as cellulosic components in blends with poly(ethylene oxide) and poly(vinyl alcohol) (PVA) to investigate the effect of hydrogen bonding in cellulose-synthetic polymer blend systems.Abstract:
Specifically substituted O-methylcelluloaea, 2,3-di-O-methylcellulose and 6-O-methylcelluloae were used as cellulosic components in blends with poly(ethylene oxide) (PEO) and poly(vinyl alcohol) (PVA). Since their hydroxyl groups (OH) form controlled intra- and intermolecular hydrogen bonds, the cellulose derivatives are useful as model compounds to investigate the effect of hydrogen bonding in cellulose-synthetic polymer blend systems. FTIR spectra of the cellulosic-PEO blend films revealed that, while the primary hydroxyl groups at the C-6 position of cellulose interact strongly with ether oxygen in PEO, the secondary hydroxyl groups at the C-2 and C-3 positions show no evidence for polymer-polymer interactionsread more

Hydrogen bonds in polymer blends
Yong He,Bo Zhu,Yoshio Inoue +2 more
TL;DR: The hydrogen bond in polymer blends is an interesting and important subject of research as its presence usually enhances the miscibility of the blend as discussed by the authors, and methods to incorporate interassociated hydrogen bonds into immiscible blends are reviewed, based on work over the last twenty or so years.
