中文摘要:
      考察逆凝聚包覆法制备的硫黄调节型粉末氯丁橡胶（PCR-121）的门尼粘度波动对其硫化胶物理性能的影响。结果表明，PCR-121生胶的门尼粘度在30～130范围内波动对其硫化胶的物理性能影响不明显；与块状CR121相比，PCR-121的加工性能和物理性能更优。对各种CR拉伸断面的形貌扫描电子显微镜观察和能谱分析结果表明，配合剂在PCR-121橡胶基体分散较好是PCR-121具有优异性能的主要原因。
英文摘要:
      The influence of the Mooney viscosity fluctuation of sulfur-modified powdered CR by reverse-coagulation cover method (PCR-121) on the physical properties of its vulcanizate was investigated.The results showed that the Mooney viscosity of PCR-121 fluctuated in the range of 30～130 had little effect on the physical properties of its vulcanizate；and PCR-121 was superior to bale CR121 in processibility and physical properties.It was found by SEM analysis and energy spectrum analysis on the tensile fractured surface of two CRs that the better dispersion of various ingredients in PCR-121 matrix resulted in superior processibility and physical properties.
