A series of hydrophobically modified water-soluble poly(vinyl alcohol) (PVA) polymers was prepared by grafting urethanized PVA with varying fractions of fatty acid chlorides of various chain lengths. The objective of the synthesis was to prepare polymers that can be applied to enhanced oil recovery.
## Abstract The surfaces of PVA fibers prepared by in situ fibrillation were modified by first crosslinking using glyoxal and then attaching cationic and anionic groups by grafting. Crosslinking prior to modification was beneficial in minimizing the solubility of the fibers in the aqueous medium in
