Özet

In this study, methylolated abietic acid and toluene diisocyanate were used together in the modification of some triglyceride oils, such as poppy seed oil, tobacco seed oil, sunflower oil, and linseed oil. For this purpose, preformed partial glyceride mixtures of each oil were, initially, partly esterified with methylolated abietic acid. Subsequently, the remaining hydroxyl groups were combined with toluene diisocyanate. In addition, toluene diisocyanate and abietic acid were reacted separately with the partial glyceride mixtures of each oil and the resulting products were used as control samples for the comparison of film properties. Another comparative sample was also prepared by reacting ester gum with linseed oil. An investigation of the film properties indicated that methylolated abietic acid could be utilized together with toluene diisocyanate as a modifier for binders based on drying and semi-drying oils.
