Processes for deactivating catalysts which may alter the polymer after formation if left in their active state. If such catalysts are acids or if acid is produced during the process of deactivation, the acid may be effectively neutralized by a catalyst deactivator represented by the general formula AaxBb1-x (OH)yCzcz·nH2O, wherein A and B are each one or more metal elements having valences a and b of 1 or 2 and 2 or 3 respectively, z=0 to (ax+b(1-x)-y)/c, x has a value of from >0 to <1, y has a value of from >2 to about ax+b(1-x)-cz, n has a value from 0 to about 1, C is an anion having a valence c of 1,2 or 3.
用于使催化剂失活的工艺,这些催化剂如果保持活性状态,在形成后可能会改变聚合物。如果这些催化剂是酸性的,或者在失活过程中产生了酸,则可以用通式 AaxBb1-x (OH)yCzcz-nH2O 所代表的催化剂失活剂来有效地中和这些酸、其中 A 和 B 分别是一种或多种
金属元素,其价 a 和 b 分别为 1 或 2 和 2 或 3,z=0 至 (ax+b(1-x)-y)/c,x 的值为 >0 至 2 至约 ax+b(1-x)-cz,n 的值为 0 至约 1,C 是一种阴离子,其价 c 为 1、2 或 3。
