Thermoplastic elastomer compositions which have good high temperature end use and good oil swell resistance are made by blending a high melting thermoplastic polymer containing a non-polar rubber and a polar rubber. Alternatively, a high melting thermoplastic polymer containing a non-polar rubber or a polar rubber or both is blended with a polyolefin thermoplastic polymer containing a non-polar rubber, or a polar rubber, or both. The composition is dynamically vulcanized. The cured multi-component thermoplastic elastomer compositions exhibit good end use properties such as hardness, tensile strength, modulus, flexibility.
将含有非极性橡胶和极性橡胶的高熔点热塑性聚合物与含有非极性橡胶或极性橡胶或两者的聚烯烃热塑性聚合物混合,可制成具有良好高温最终用途和良好耐油膨胀性的热塑性弹性体组合物。或者,将含有非极性橡胶或极性橡胶或两者兼有的高熔点热塑性聚合物与含有非极性橡胶或极性橡胶或两者兼有的聚烯烃热塑性聚合物混合。组合物经过动态硫化。固化后的多组分热塑性弹性体组合物具有良好的最终使用性能,如硬度、拉伸强度、模量和柔韧性。
