摘　　要：采用差示扫描量热法测定了ABS树脂的氧化诱导时间。讨论了在氧化诱导时间测试过程中的各种影响因素，确定了适当的测试条件。提出了使用氧化诱导时间测试方法需注意的问题。方法简单快速，重复性好，相对标准偏差小于5％。The oxidation induction time of ABS was measured by differential scanning calorimetry （DSC）. Various factors affecting the measurement results were discussed and the appropriate measurement conditions were selected. Some questions in using oxidation induction time measurement method of DSC are noted. The method is simple and rapid and the reproducibility is good. The RSD is less than 5 %.
