Abstract: Two methods which were derived from the temperature and apparent activation energy at glass transition and from VFT equation were used to calculate the viscoelastic coefficients in WLF equation.The viscoelastic coefficients of ten systems were calculated with the two methods respectively.The results show that the WLF equation can be obtained by DSC,and the viscoelastic coefficients obtained from three methods are in good agreement

摘要： 通过玻璃化转变温度和表观活化能以及由ＶＦＴ方程导得ＷＬＦ方程粘弹系数的两种新计算方法。用该方法分别计算１０个体系的粘弹系数，结果表明，用ＤＳＣ技术可以获得ＷＬＦ方程，３种计算方法获得的粘弹系数符合较好。
