| titleOfInvention | Method of catalyst deactivation |
| abstract | ABSTRACT OF THE DISCLOSURE An improved method of terminating ethylene polymerization and interpolymerization reactions by deactivating the Ziegler-type catalyst used in the reaction comprises the step of injecting a selected deactivating agent into the molten polymer solution in the polymerization reactor prior to degassing of the polymer solution. The deactivating agent is selected from the group consisting of: (a) natural hydrotalcite minerals and synthetic hydrotalcite-like materials; b) Group IIIA metal salts of monocarboxylic acids; (c) alkali metal and alkaline earth metal salts of alkarylsulfonic acids; (d) alkali metal and alkaline earth metal salts of alkyl and alkaryl sulfuric acids; (e) organophosphites of a formula selected from the group consisting of (RO)3P and (RO)2POH where R is a hydrocarbon group containing 1 to 22 carbon atoms, inclusive; (f) ethoxylated hydrocarbylamines of the formula R'3_nN[(OCH2CH2)moH]n where R' is hydrogen or a hydrocarbon group containing 1 to 22 carbon atoms, inclusive, and at least one R' is a hydrocarbon group, n is 1 or 2, and m is an integer between 1 and 22, inclusive; (g) monocarboxylic acid esters of triethanolamine of the formula (RCOOCH2CH2)3N where R is a hydrocarbon group containing 1 to 22 carbon atoms, inclusive; and (h) organotin salts of maleic acid of the formula [-Sn(R)200CCH=CHCOO-] where R is a hydrocarbon group containing 1 to 22 carbon atoms, inclusive. |
