摘要
着重讨论了双螺杆连续化工艺合成的聚乙二酸丁二酯型TPU及其常温下的物理机械性能、热性能及其老化性能。并以此来指导我们的加工和应用。
The Twin-screw successive reactive extrusion technique are introduced. Thermoplastic polyurethane elastomers(TPUs) based on PBAG,MDI and 1, 4-BD were prepared by both small and middle twin-screw extruder. The mechanical, thermal and ageing properties of these TPUs were determined,and the resuts are discussed.
