The present disclosure provides cis-polycycloolefins and methods for forming cis-polycycloolefins typically having 50% or greater cis carbon-carbon double bonds comprising contacting a first cyclic hydrocarbyl monomer with a catalyst represented by Formula (I):
wherein: M is a group 8 metal; Q1, Q2, and Q3 are independently oxygen or sulfur; each of R1 and R4 is a halogen; R9 is C1-C40 hydrocarbyl or C1-C40 substituted hydrocarbyl; and each of R2, R3, R5, R6, R7, R8, R10, R11, R12, R13, R14, R15, R16, R17, R18, and R19 is independently hydrogen, halogen, C1-C40 hydrocarbyl or C1-C40 substituted hydrocarbyl. In at least one embodiment, a polycyclopentene has 50% or greater cis carbon-carbon double bonds.
本公开提供了顺式聚环烯烃和形成通常具有 50% 或更多顺式碳碳双键的顺式聚环烯烃的方法,包括将第一环烃单体与由式 (I) 所代表的催化剂接触:
其中M 是第 8 族金属;Q1、Q2 和 Q3 独立地是氧或硫;R1 和 R4 各自是卤素;R9 是 C1-C40 烃基或 C1-C40 取代的烃基;以及 R2、R3、R5、R6、R7、R8、R10、R11、R12、R13、R14、R15、R16、R17、R18 和 R19 各自独立地是氢、卤素、C1-C40 烃基或 C1-C40 取代的烃基。在至少一个实施方案中,聚环戊烯具有 50% 或更多的顺式碳碳双键。
