摘　　要：In this study, gasoline was blended with dimethyl carbonate, ethyl acetate or methyl acetate respectively with four different volume fraction, i.e. 1%, 3%, 5% and 10%. The nitrile-butadiene rubber (NBR), fluorocarbon rubber (FKM), and Silastic were prepared for the immersion tests. To assess the performance of the three ester additives, the changes in the weight and volume of these three elastomers during the immersion tests with different gasoline samples were studied. The results showed that gasoline blended with the ester additives could lead to serious swelling problem for the elastomer materials which were widely used in the vehicle manufacture industry. The seal ability of elastomer materials would also be impaired by being exposed in the ester additives-gasoline blending for a long time.In this study, gasoline was blended with dimethyl carbonate, ethyl acetate or methyl acetate respectively with four different volume fraction, i.e. 1%, 3%, 5% and 10%.
