The interface behavior between essence and ethylene-vinyl acetate copolymer pallets was studied so that necessary data were obtained to guide the preparation of fragrant masterbatch．The adsorption typeand wettability between essence and the copolymer pallets were analysed by measurements of fouriertransform infrared spectrum,surface tension,contact angle and specific surface area．The technical factorsaffecting absorptivity such as the charge ratio,temperature,pressure and stirring speed were studied by series of adsorption experiments The results showed that the adsorption of essence on the surface of ethylene-vinyl acetate copolymer pallets is physical in nature Essence couldn’t moisten the surface of ethylene-vinyl acetate copolymer pallets absolutely,but it could be soaked into the surface of the pallets partly．Adsorptivity could be increased by enhancing the temperature,pressure and stirring speed,but the extension of adsorption time had little influence on adsorptivity．
