通过测试共聚PP和均聚PP在不同测试条件下的脆化温度，讨论了脆化温度测试的相关影响因素。结果表明，冷冻时间、试样厚度及退火处理等都会对测试结果产生影响。冷冻时间变长会使脆化温度测试结果偏高；试样厚度越大，测得的脆化温度越高；退火对结晶型材料影响较大，而且结晶度越高，退火的影响越大。

The influencing factors on the plastic's brittleness temperature testing results were studied by testing homo-polypropylene and co-polypropylene in different measurement conditions.The result shows that freezing time , the thickness of samples and annealing treatment affects testing results.The brittleness temperature results increase as the freezing time elongated.The thickness of the sample is greater ,the brittleness temperature is higher.Annea-ling has great effect on the crystalline material ,and higher the degree of crystallization results greater the influence of annealing.
