摘　　要：为定量分析聚合反应倾向、优化反应加工条件,在建立紧密啮合同向旋转双螺杆挤出机的反应器模型及物料的化学反应动力学模型、化学流变模型的基础上,分析了阴离子聚合反应挤出过程的化学热效应,推导出反应热的释放量与反应热强度的数值计算式,并通过算例展示了其变化特点。In order to quantitatively analyze polymerization tendency and optimize reactive processing conditions, the chemical calorific effect during the reactive extrusion process for anionic polymerization was analyzed based on the reactor model of closely intermeshing co-rotating twin screw extruders, kinetic model of anionic polymerization and chemorheological model of fluids in extruders. A numerical computation equation for calculating the heat release and calorific intensity of reaction was deduced. The variation features of these two thermal parameters were demonstrated via the computational examples.
