摘要: 用基团分析方法对端羟基聚丁二烯（ＨＴＰＢ）／己二异氰酸酯（ＨＤＩ）体系的本体聚合反应的动力学进行了研究。探讨了催化剂二丁基二月桂酸锡（ＤＢＴＤＬ）对反应速度的影响。结果表明，催化体系的聚合反应速度完全满足双螺杆挤出机反应挤出停留时间的要求。『Abstract: Reactive kinetic of bulk polymerization of HDI/HTPB was studied by means of titration analysis.The effect of catalyst DBTDL was detailed. Results show that the reactive speed of catalysed system can meet the retention time of reactive extrusion based on t
