Patent ID: 8604118

Claim:
A process for producing a copolymer comprising: introducing an active polymer from a first polymerization reactor into a second polymerization reactor; contacting the active polymer with at least one olefin under polymerization conditions in the second polymerization reactor to form a heterophasic copolymer that is a sticky polymer; continuously adding a multicomponent antifoulant directly to the second polymerization reactor at a rate such that the multicomponent antifoulant is present in the heterophasic copolymer in a concentration from about 25 ppm to about 200 ppm; and inhibiting, with the multicomponent antifoulant, fouling within the second polymerization reactor; and forming a sticky polymer having an Fc greater than 30% and a minimum bin opening for free flow at zero storage time of 2 feet.
