Dilute solution viscometry was used to monitor the drying of the oils of linseed ( Linum usitatissimum L.), rubber ( Hevea bransiliensis [Kunth] Muell. Arg.), soyabean ( Glycine max (L) Merr) and melon ( Colocynthis vulgaris Schrad) with a view to gain insight into the mode of network formation prior to the gel point. Intrinsic viscosity values obtained show a rise‐and‐fall pattern which was attributed to the occurrence of inter‐ and intramolecular crosslinking. Reduced viscosity values of the solutions of the oils (in both their oxidized and unoxidized forms) show a rise with dilution, indicating the occurrence of major structural changes in the system.
