| 摘 要： | 以CPE和CPE／HPVC为改性剂，用熔融共混的方式对TPU的共混体系进行了系统的研究。对TPU／CPE和TPU／CPE／HPVC共混体系的力学、耐寒及流变性能进行了测试及分析。实验结果表明：CPE及CPE／HPVC的加入，虽使体系的力学性能有所降低，但能明显改善TPU的加工性能，并且基本保持了TPU优异的耐寒性。

| Abstract: | Thermoplastic polyurethane elastomer(TPU) with chlorinated polyethylene (CPE) and CPE/HPVC (high molecular weight PVC) as modifiers was studied systematically by melt blending.Mechanical properties,cold resistance and rheological behavior of TPU/CPE and TPU/CPE/HPVC blends were measured and analyzed.The results indicate that with the incorporation of CPE and CPE/HPVC,the mechanical properties of the blends decreased lightly,but the processability of TPU was significantly improved and the cold resistance of TPU was not changed basically. |
