A compound useful as a catalyst activator corresponding to the formula:
(A*
+a
)
b
(Z*J*
j
)
−c
d
,
wherein:
A* is a cation of charge +a,
Z* is an anion group of from 1 to 50 atoms not counting hydrogen atoms, further containing two or more Lewis base sites;
J* independently each occurrence is a Lewis acid coordinated to at least one Lewis base site of Z*, and optionally two or more such J* groups may be joined together in a moiety having multiple Lewis acidic functionality,
j is a number from 2 to 12 and
a, b, c, and d are integers from 1 to 3, with the proviso that a×b is equal to c×d.
一种有用的催化剂活化剂化合物,其化学式为:(A*+a)b(Z*J*j)−cd,其中:A*是带有+a电荷的阳离子,Z*是一个含有1至50个原子(不包括氢原子)的阴离子基团,进一步包含两个或更多的Lewis碱基位点;J*是独立的,每次出现时都是与Z*的至少一个Lewis碱基位点配位的Lewis酸,而且可选地,两个或更多这样的J*基团可以连接在一起,形成具有多个Lewis酸性功能的基团,j是从2到12的数字,a、b、c和d是从1到3的整数,但是a×b等于c×d。
