  摘要：

  分支：线性聚合物的迁移率在分支时发生变化，这对可加工性和可拉伸性具有显着影响。通过先进的固态NMR光谱研究了规则支化的模型聚烯烃，并鉴定了结晶区域分支周围的扭曲缺陷。对于较低的分支含量，扭转运动是解耦的。对于更高的内容，可以找到集体运动（参见图片）。

  Grubbs olefin metathesis catalyst was immobilized as a ruthenium-supported ionic liquid catalyst (Ru-SILC) in pores of amorphous alumina with the aid of ionic liquid [hmim]PF6. This Ru-SILC was effective for various olefin metathesis reactions such as intra- or intermolecular macrocyclization and dimerization, and used up to six times after simple decantation.

  在离子液体 [hmim]PF6 的帮助下，将 Grubbs 烯烃复分解催化剂固定在无定形氧化铝孔隙中作为钌支撑离子液体催化剂（Ru-SILC）。这种 Ru-SILC 对分子内或分子间的大环化和二聚化等各种烯烃偏析反应都很有效，简单倾析后可使用六次。

  The present invention is related to a linear functional polymer having repeating units A, B and D. Unit A represents —CH 2 —, unit B represents and unit D represents where R 1 represents a polar functional group. There are at least four A units separating each B unit, each D unit, and each B and D unit. The value y represents the total number of B units and is an integer greater than or equal to 1. The total number of D units is represented by h and is an integer greater than or equal to 0. And x represents the total number of A units and is an integer sufficient that the molar fraction of the B and D units in the linear functional polymer is represented by a value j defined by the equation: j = y + h x + y + h ≤ 0.032 . The present invention is also directed to a method for preparing such linear functional polymers by copolymerizing a first polar substituted monomer and a second non-polar unsubstituted monomer.

  本发明涉及一种具有重复单元A、B和D的线性功能聚合物。单元A代表—CH2—，单元B代表，单元D代表其中R1代表极性官能团。每个B单元、每个D单元和每个B和D单元之间至少有四个A单元。值y表示B单元的总数，是大于或等于1的整数。D单元的总数由h表示，是大于或等于0的整数。x表示A单元的总数，是一个足够使线性功能聚合物中B和D单元的摩尔分数由方程式j定义的整数，j=y+hx+y+h≤0.032。本发明还涉及一种制备这种线性功能聚合物的方法，通过共聚第一极性取代单体和第二非极性未取代单体。
