中文摘要:
      采用甲基丙烯酸甲酯（MMA）和丙烯酸丁酯（BA）对淀粉进行接枝改性，通过共沉法制备淀粉-g-MMA-BA/NR复合材料，并对复合材料的物理性能和动态力学性能进行研究。结果表明，改性后的淀粉结晶区被破坏，与NR的相容性提高；与NR胶料相比，淀粉-g-MMA-BA/NR复合材料的物理性能和抗湿滑性能有所提高，滚动阻力变化不明显。
英文摘要:
      The starch was grafted with methyl methacrylate（MMA） and butyl acrylate（BA），a starch-g-MMA-BA/NR composite was prepared by coprecipitation method，and the physical properties and dynamic mechanical properties were investigated.The results showed that the crystallization fields of starch were destroyed after modification，and the compatibility between the modified starch and NR was improved；the physical properties and wet skid resistance of starch-g-MMA-BA/NR composite improved，and the rolling resistance changed a little when compared to that of the NR compound.
