Abstract
In the production of ethylene-vinyl acetate copolymers in a free radical catalyst initiated high pressure process, explosive decomposition is prevented by contacting the reactor effluent downstream of the reactor outlet with small amounts of a hindered phenolic compound, separating unreacted monomer from the mixture of copolymer, unreacted monomer and scavenger in a separation zone and recycling the separated monomer to the reactor.
