1、天津大学博士学位论文炭黑的表征技术与接枝高分子技术的研究姓名：王道宏申请学位级别：博士专业：工业催化指导教师：张继炎20020915对于炉法炭黑，接枝聚乙二醇显著降低了其分散颗粒的粒度。分散效果随接枝聚乙二醇分子量的不同而存在差异。实验结果表明，较高的分子量有利于接枝炉法炭黑的分散。同时接枝聚乙二醇使接枝的炉黑颗粒在水中以及异雨醇中能够长时间稳定地分散，而且接枝高分子的分子量较大时，这一效果更加明显。对于接触法炭黑，接枝聚乙二醇没有降低炭黑在水中的分散颗粒粒度的效果。接触法炭黑在水中、异丙醇中的

2、分散稳定性也没有因为接枝聚乙二醇后得到进一步的改善。关键词：炭黑，表征，酸性含氧基团，高分子接枝炭黑，聚E,--醇，分散性能AbstractThecarbonblackpigmentscarlbeappliedtomanyindustrialfields，suchasprinting，coating，plasticsandetc．nlestudyonthecharacterizationmethodsiSimportantmeansandscientificbaseforresearchandd
