A compound useful as a cocatalyst or cocatalyst component, especially for use as an addition polymerization catalyst compound, corresponding to the formula:
(A*
+a
)
b
(Z*J*
j
)
−c
d
,
wherein:
A* is a cation of from 1 to 80, preferably 1 to 60 atoms, not counting hydrogen atoms, said A* having a charge +a,
Z* is an anion group of from 1 to 50, preferably 1 to 30 atoms, not counting hydrogen atoms, further containing two or more Lewis base sites;
J* independently each occurrence is a Lewis acid of from 1 to 80, preferably 1 to 60 atoms, not counting hydrogen atoms, 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, and provided further that one or more of A*, Z* or J* comprises a hydroxyl group or a polar group containing quiescent reactive functionality.

(A*
+a
)
b
(Z*J*
j
)
-c
d
,
其中
A* 是含有 1 至 80 个原子,最好是 1 至 60 个原子(不包括氢原子)的阳离子,所述 A* 带有电荷+a、
Z* 是 1 至 50 个原子,最好是 1 至 30 个原子(不包括氢原子)的阴离子基团,进一步含有两个或更多的路易斯碱位点;
每个独立出现的 J* 是 1 至 80 个原子(最好是 1 至 60 个原子)(不计氢原子)的路易斯酸,与 Z* 的至少一个路易斯碱位点配位,可选择将两个或多个这样的 J* 基团连接在一起,形成具有多个路易斯酸官能团的分子、
j 是 2 到 12 之间的数字,且
a、b、c 和 d 是 1 至 3 的整数,但 a×b 等于 c×d,而且 A*、Z* 或 J* 中的一个或多个包含羟基或含有静止反应官能团的极性基团。
