  Several low-molar-mass alkyl iodides were studied as initiating dormant species in living radical polymerization with organic catalysts. Primary, secondary, and tertiary alkyl iodides with different stabilizing groups (ester, phenyl, and cyano groups) were systematically studied for the rational design of initiating alkyl iodides. The activation rate constants of these alkyl iodides were experimentally

  研究了几种低摩尔质量的烷基碘，它们是在有机催化剂的活性自由基聚合中引发休眠的物质。为了合理设计引发烷基碘，系统地研究了具有不同稳定基团（酯，苯基和氰基）的伯，仲和叔烷基碘。通过实验确定这些烷基碘的活化速率常数，以进行定量比较。这些烷基碘用于甲基丙烯酸甲酯和丙烯酸丁酯的聚合反应中，以检查它们在这些聚合反应中的引发能力。使用具有官能团的烷基碘来制备远螯聚合物。还研究了具有多个起始位点的烷基碘。

  indicating that the γ-butyrolactone units could endure the polymerization and hydrogenation. Polymers catalyzed by Grubbs II catalyst suffer from chain heterogeneity due to severe olefin isomerization. Thermal properties of the polymers were investigated via thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC). TGA measurements show that these polymers are stable up to 350 °C. DSC

  介绍了通过无环二烯复分解聚合（ADMET）合成的含γ-丁内酯的新型周期性共聚物的合成及其热性能。设计了两个对称的二烯单体M6和M8。两种单体均包含两个γ-丁内酯单元，但环状结构和末端烯烃之间的亚甲基间隔基的长度不同。单体是通过两步法制备的。首先是二乙基内消旋体的原子转移自由基加成（ATRA）用-1，5-己二烯或1，7-辛二烯进行-2，5-二碘己二酸二酯，得到含有两个γ-碘酯序列的中间体。随后，通过加热，通过分子内环化将特定序列转化为γ-丁内酯单元。两种单体使用两种Grubbs催化剂（格鲁布斯I和II格鲁布斯）以产生四种聚合物聚合以中等至高分子量（P6-1，P6-2，P8-1，以及P8-2）并氢化得到最终的饱和聚合物。已经获得了预期的周期性共聚物，并用多种方法对其进行了表征，表明γ-丁内酯单元可以承受聚合和氢化反应。由于严重的烯烃异构化，由Grubbs II催化剂催化的聚合物具有链不均一性。

  A lubricating oil additive containing at least one acrylic block copolymer having a weight-average molecular weight of 10,000 to 1,000,000 and a molecular weight distribution [ratio of weight-average molecular weight (Mw) to number-average molecular weight (Mn), i.e. Mw/Mn ratio] of 1.5 or below and lubricating oil compositions containing the additive. The lubricating oil additive exhibits a thickening effect higher than those of conventional acrylic lubricating oil additives and can improve the viscosity index of lubricating oil even when added in a small amount. Further, the additive can also improve the low-temperature characteristics, flow characteristics, and shear stability. The lubricating oil compositions enable energy saving and can lengthen the lifetime of lubricating oil and reduce the load on the global environment.
