The influence of poly(vinyl alcohol), PVA, molecular weight on drop breakage and coalescence in stirred liquid–liquid dispersion was considered. Three types of PVA of the same degree of hydrolysis 88% and different molecular weights in the range 13,000–186,000 were used in experiments. ...
Polyvinyl alcohol(PVA) of two molecular weights was used to prepare shape memory polymers based on chemical-crosslinking by glutaraldehyde.The chemical-crosslinking was done in the presence of 2-carboxyethvl acrylate oligomers(CEA) and nano-filler[multi-wall carbon nanotubes(MWCNT) and functionalized...

Poly(vinyl alcohol) is a complex, multicomponent material exhibiting a number of broad molecular property distributions and is therefore difficult to characterize by simple analytical techniques. Molecular weight distribution can be measured by aqueous size exclusion chromatography methods but the choice of...
