摘要：以聚苯乙烯（PS）低聚物为相容剂，用熔体插层法制备SBR/有机蒙脱土（OMMT）纳米复合材料，并对其结构及性能进行研究。结果表明，PS大分子能够插入OMMT层间形成复合物；采用熔体插层法使PS/OMMT纳米复合物在SBR基体中实现纳米级分散，可间接实现OMMT在SBR基体中的纳米级分散；当填充5份OMMT时，SBR/OMMT纳米复合材料具有较好的物理性能。

摘要：采用透射电子显微镜、扫描电子显微镜、能量色散谱仪和动态粘弹谱仪分析氨水改性高岭土/NR复合材料的微观结构。结果表明，与采用凝聚法简单共混制备的高岭土/NR复合材料（CKNR）相比，采用凝聚共沉法制备的氨水改性高岭土/NR复合材料（NKNR）中高岭土粒子分布更均匀，平均粒径较小；NKNR的拉伸断面布满了直径约为50 nm的拉丝，这些拉丝是高岭土/NR界面附近的NR与高岭土表面凝胶的分子水平复合物；NKNR中的NR具有多种聚集态，包括NR基体、远程NR与高岭土表面凝胶复合物以及高岭土/NR界面附近的NR与高岭土表面凝胶复合物。

摘要：提出用硫化返原率曲线表征胶料的抗硫化返原性能的观点。硫化返原率曲线可以清晰地反映胶料的硫化返原过程和准确表征其抗硫化返原性能，可以作为抗硫化返原剂或胶料的特征曲线；不同抗硫化返原剂的作用机理决定了它们的抗硫化返原效果及其应用场合。

Abstract:A new method for characterizing the antireversion of rubber compound with the reversion percentage curve has been proposed.The antireversion course of rubber compound can be clearly reflected and its antireversion behaviour can be correctly characterized by the reversion percentage curve,which can be used as the characteristic curve of antireversion agent or rubber compound.The antireversion effectiveness and suitable application of various antireversion agents depend on their mechanism.
