| titleOfInvention | Polymer finishing process |
| abstract | A finishing process for a polymer containing an active catalyst residue comprising the following steps:n (i) introducing one or more ethylenically unsaturated monomers, a transition metal catalyst system, and, optionally, hydrogen into one or more reaction zones in such amounts and under such polymerization conditions that a polymer will be produced having a crystallinity of less than about 10 percent by weight; (ii) maintaining the reaction zone(s) at a temperature below the sticking temperature of the polymer and in an essentially oxygen-free atmosphere; (iii) introducing into the reaction zone(s) (a) 2,6-di-tert-butyl-4-alkyl phenol and/or alkyl-3-(3-5-di-tert-butyl-4-hydroxy phenyl)-propionate wherein the alkyl group has 1 to 20 carbon atoms and is linear or branched chain, or a complex thereof, and (b) zinc oxide; a hydrotalcite containing magnesium, aluminum, and/or zinc cation(s); or a zeolite containing sodium, calcium, magnesium and/or zinc cation(s) in sufficient amounts to stabilize the polymer and neutralize acid formed in the post-reaction zone(s); (iv) recovering the polymer from the reaction zone(s) and passing the polymer into one or more post-reaction dry-blending zones, said zone(s) being maintained at a temperature below the sticking temperature of the polymer and in an essentially oxygen-free atmosphere; (v) contacting the polymer with water in an amount sufficient to hydrolyze any catalyst residue and liberate complexed phenolic compound(s); (vi) introducing into the post-reaction zone(s), one or more catalyst deactivator compounds in an amount sufficient to essentially deactivate the hydrolyzed residue of the transition metal catalyst system; and (vii) introducing into the post-reaction zone(s), one or more thermal and/or photo-oxidation stabilizers in an amount sufficient to substantially prevent the thermal and photo-oxidation of the polymer. |
