SummaryIt can be stated that the polymerization rate of safflower oil is sufficiently rapid to warrant its use on a commercial scale. Furthermore, with the proper choice of polymerization temperature, safflower can be bodied at the same rate as linseed. The increasing rate at which safflower bodies in the high viscosity ranges invites further investigation. In these higher viscosity ranges the iodine value continues to drop whereas in the same range the iodine numbers of other oils show a tendency to approach an asymptotic value.Safflower heat bleaches considerably better than linseed and is also equal to or better than soya in this respect.
