Process for inhibiting cross-linkages in polyethylene by the use of alkylated hydroxyanisoles or substituted phenyl amines

Claim 1

IN A PROCESS FOR INHIBITING THE DEGRADING INFLUENCE OF AND THE FORMATION OF CROSS-LINKAGES BY ETHYLENE POLYMERIZATION CATALYSTS ON ETHYLENE POLYMERS AFTER THE POLYMERIZATION REACTION HAS BEEN CONDUCTED AT A TEMPERATURE UP TO 240*C., UNDER PRESSURES BETWEEN 30 AND 3,000 ATMOSPHERES IN THE PRESENCE OF AN ETHYLENE POLYMERIZATION CATALYST AND DURING THE DISCHARGE OF THE REACTION MIXTURE FROM THE REACTION ZONE, THE STEP WHICH COMPRISES ADDING TO THE REACTING MIXTURE AS IT IS BEING DISCHARGED FROM THE ZONE OF REACTION, A POLYMERIZATION DECELERATOR IN SUFFICIENT AMOUNTS TO DESTROY THE EFFECTIVENESS OF THE CATALYST AND ALSO IN SUFFICIENT AMOUNTS TO INHIBIT CHAIN BRANCHING, CROSS-LINKING AND OXIDATION OF THE ETHYLENE POLYMER PRODUCED.
