摘　　要：将液体丁腈橡胶-26溶解于丙酮中,采用稀释法测定试样的特性黏数,同时计算出Huggins方程和Kraemer方程的κ,β常数,当二者满足0.180≤κ≤0.472,κ+β≈0.5,可以用快速法计算液体丁腈橡胶-26的特性黏数。结果表明,快速法相对误差小于3%,最大标准偏差小于0.150%。The intrinsic viscosity of liquid acrylonitrile- butadiene rubber- 26 was determined by dilution method with acetone as solvent, and the constants κ,β in Huggins and Kraemer equations were calculated. When κ and β met 0.180≤κ≤0.472,κ＋β≈0.5 the rapid method could be used to calculate intrinsic viscosity of liquid acrylonitrile - butadiene rubber - 26. The relative error and the standard deviation of the rapid method were less than 3% ,0. 150% respectively.
