The first example of a 3-alkene polymerization has been successfully achieved with 3-heptene in the presence of phenyl-substituted α-diimine nickel precatalysts activated by dMMAO, and compared with the corresponding linear alkenes, i.e., 1-pentene, 2-hexene and 4-octene polymerizations. The microstructures of the produced poly(3-heptene), which consists of ethyl, propyl and butyl branches indicated the 3,4- and 4,3-insertion, followed by chain-walking, with incorporation of a small fraction of long methylene sequences of 1,7-enchainment via monomer-isomerization.

Late-transition metal catalyzed polymerization reactions of internal alkenes to synthesize novel polyolefin materials are highly important and also highly challenging. Upon activation with dried modified methylaluminoxane (dMMAO), the first example of a 3-alkene polymerization has been successfully achieved for 3-heptene catalyzed by phenyl-substituted α-diimine nickel complexes in comparison, and compared with the polymerizations of the corresponding linear alkenes, i.e., 1-pentene, 2-hexene and 4-octene. The results indicate that the polymerization of 3-heptene was achieved via chain-walking to generate branched amorphous polymers with glass transition temperature of ca. −68 °C. The microstructures of the produced poly(3-heptene) indicated the 3,4- and 4,3-insertion followed by chain-walking, the latter being predominant. The NMR analyses of the polymers showed that the obtained poly(3-heptene) possessed ethyl, propyl and butyl branches and a small amount of the long methylene sequence of 1,7-enchainment via monomer-isomerization. The branches structures were significantly dependent on the polymerization temperature, and the content of propyl branches derived from 3,4-insertion decreased with an increase in the polymerization temperature.

在由dMMAO活化的苯基取代的α-二亚胺镍预催化剂存在下，用3-庚烯成功地完成了3-烯烃聚合的第一个例子，并与相应的线性烯烃（即1-戊烯，2-己烯）进行了比较。和4-辛烯聚合。所产生的由乙基，丙基和丁基支链组成的聚（3-庚烯）的微观结构表明有3,4-和4,3-插入，随后进行链步，并掺入了一小部分长的亚甲基序列通过单体异构化的1,7链。

内部烯烃的后过渡金属催化的聚合反应以合成新型的聚烯烃材料是非常重要的，也是极富挑战性的。用干燥的改性甲基铝氧烷（dMMAO）活化后，已成功实现了由苯基取代的α-烯烃催化的3-庚烯的3-烯烃聚合反应的第一个实例。比较并与相应的直链烯烃，即1-戊烯，2-己烯和4-辛烯的聚合进行比较。结果表明3-庚烯的聚合是通过链走反应实现的，以产生玻璃化转变温度为约120℃的支链无定形聚合物。−68°C。所产生的聚（3-庚烯）的微观结构表明3,4-和4,3-插入后接着链行走，后者是主要的。聚合物的NMR分析表明，所获得的聚（3-庚烯）具有乙基，丙基和丁基支链以及少量的通过单体异构化的1,7-链长的亚甲基序列。支链结构很大程度上取决于聚合温度，并且衍生自3的丙基支链的含量：
