摘　　要：采用理论计算和溶胀实验,研究了Levapren400,Levapren450,Levapren500和Levapren600 4种牌号的乙烯-醋酸乙烯酯共聚物(EVM)的溶解度参数。结果表明,4种不同醋酸乙酯含量的EVM,具有相似的溶胀性能,其溶解度参数的实验测定值与理论计算值相符,在18.00～21.00(J/cm3)1/2之间。确定了4种牌号EVM的良溶剂有甲苯(18.16)、氯仿(18.95)、四氢呋喃(19.46)、氯苯(19.58)和二氯甲烷(19.82)。The solubility parameters of ethylene-vinyl acetate rubber （EVM） of Levapren400, Levapren450, LevaprenS00 and Levapren600 by theoretical calculation and swelling test were studied. The results showed that the four kinds of EVM with different vinyl acetate content had similar swelling properties, the test values of solubility parameters coincided with the theoretical calculation values, which was among 18.00-21.00（J/cm^3）1/2. It was determined that the good solvents for these four grades of EVM included toluene, chloroform, chlorobenzene and dichloromethane.
