ABSTRACT:
A process for the production of a catalyst precursor comprising reacting (a) a metallocene dihalide; (b) a compound of the formula: ##STR1## wherein each Q is the same or different and is independently selected from the group consisting of O, NR, CR.sub.2, and S; E is either C or S; Z is selected from the group consisting of --OR, --NR.sub.2, --CR.sub.3, --SR, --SiR.sub.3, --PR.sub.2, --H, and a substituted or unsubstituted aryl group; and each R is independently a group containing carbon, silicon, nitrogen, oxygen, and/or phosphorus; and (c) a trialkylamine.
