Abstract: The commercial epoxidized and with butanol esterified soybean and sunflower oil was by means of epoxy groups chemically modified with low-molecular compounds having a dissociating hydrogen. Compounds containing in their molecules nitrogen, sulfur, chlorine, bromine, and phosphorus atoms were bonded on the oil, whereby it is possible to consider for most of them a special effect. The molecular mass increase of modified soybean oil was reached by transforming it into a magnesium,, calcium, strontium, barium, zinc or bismuth salt. The thermal analysis has proved that these materials can be used as nonvolatile additives for polymers processed at enhanced temperatures, which is closely linked with the creation and protection of the environment. The conditions of this general method for fixation of compounds on carriers of epoxidized groups, rate constants of reaction and the mechanism of its catalysis were discussed.
