Abstract

The invention provides a composition comprising at least the following: an oil, and at least one compound selected from Compounds 1 through 3, or a combination thereof, as described herein. The composition can be used to improve the high pressure, free-radical polymerizations of ethylene-based interpolymers, and to reduce polymer build-up in reciprocation devices throughout the process.
