Process for deactivating and neutralizing polymerization catalysts.

摘要

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 Aa_xB1_b-x (OH)yCc_z.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.
