A process for producing a heterophasic copolymer is provided. The process includes introducing an antifoulant to a second polymerization reactor which operates in series with a first polymerization reactor. The antifoulant may be a multicomponent antifoulant and/or a coating agent. Provision of either antifoulant enables the production of a heterophasic copolymer with an Fc value from about 10% to about 50% by inhibiting reactor fouling during polymerization.
