摘要 介绍了用液闪计数器测定生物基材料中生物基质量分数的原理。利用该方法测定了不同淀粉比例的聚乙烯和淀粉共混物(PE/St)、聚丙烯和淀粉共混物(PP/St)、聚丁二酸丁二酯和淀粉共混物(PBS/St)、聚对苯二甲酸/己二酸/丁二酯和淀粉共混物(PBAT/St)中生物基的质量分数,将测试结果和理论生物基质量分数相比较,最大偏差为12.6%,符合ASTM D6866中测试结果需要在15%以内的要求。 The principle of determining the biobased content of biobased material with liquid scintillation counter is introduced in this study.The biobased contents of PE/St,PP/St,PBS/St and PBAT/St,with different amount of starch,are measured by this method,respectively.The maximum difference between determined biobased contents and the theoretical ones is 12.6%,which can meet the requirement in ASTM D 6866(15%).
