Abstract: A process for the in-reactor stabilization of an alpha olefin comprising the steps of sequentially:adding alpha olefin monomer into a polymerization reactor;adding a mixture of selectivity control agent and cocatalyst to the polymerization reactor;adding a procatalyst to the polymerization reactor;injecting an alkyl-aluminum-antioxidant into the polymerization reactor;injecting an acid acceptor into the polymerization reactor; andpolymerizing the monomers in the reactor.
