Effect of crosslinking on the mechanical and thermal properties of poly(vinyl alcohol)

Poly(vinyl alcohol) was crosslinked with hexamethylene diisocyanate in solution. The variation of the thermal and mechanical properties with the crosslinking density show an initial decrease due to the diminution in the crystallinity of the system, caused by the crosslinking. After an abrupt rise at...

Zusammenfassung:Poly(vinyl alcohol) was crosslinked with hexamethylene diisocyanate in solution. The variation of the thermal and mechanical properties with the crosslinking density show an initial decrease due to the diminution in the crystallinity of the system, caused by the crosslinking. After an abrupt rise at about 20%, the properties tend to level off independently on the increase of the crosslinking. (Original abstract - amended)
