极性橡胶 polar rubber
- 基体橡胶极性是影响该演化过程的关键因素。
The transformation was determined by polarity of rubber. - 较高极性的脲键给聚合物提供了较强的氢键和较好的热稳定性,并使这些聚合物在橡胶平台区有较高和变化较小的动态剪切模量。
The highly polar urea linkage offers stronger hydrogen bonding and higher thermal stability to the polymers, which introduces higher and flatter shear modulus the rubbery plateau. - 采用溶液法,选用极性单体马来酸酐(MAH),在非隔氧条件下,以过氧化苯甲酰( BPO)为引发剂对天然橡胶(NR)进行接枝改性。
The graft copolymerization of natural rubber(NR) and polar monomer maleic anhydride (MAH)in the presence of oxygen has been studied in toluene solution.
