ABSTRACT:
A method for inhibiting polymer build-up in a recycle line and a heat exchanger during a polymerization process of one or more alpha olefins, particularly sticky polymers, which method comprises introducing as an antifouling an alcohol having 1 to 10 carbon atoms, an alkyl or cycloalkyl ether having 2 to 20 carbon atoms, or a mixture thereof at one or more locations in the recycle gas line in an amount sufficient to inhibit polymer buildup.
