Abstract
A method of stabilizing radical ethylene copolymerization reactions for approximately 5 to 10 minutes, the method including using a phenolic compound with other comonomers and performing the radical ethylene copolymerization reactions at high pressure. Also, a method of preparing an ethylene copolymer at high pressure in the presence of one or more phenolic compounds, as defined below, and one or more initiators.
