摘要：
The present invention provides a method for manufacturing an ethylene-vinyl acetate copolymer (EVA) in a polymerization solution in a vessel. The polymerization solution includes ethylene, vinyl acetate, methanol and a polymerization initiator. This method includes: cooling a gas including a vapor evaporated from the polymerization solution whereby to produce a condensate of at least a portion of said gas, and introducing said condensate into the polymerization solution whereby to evaporate at least one component in said condensate. Said vapor includes said at least one component.
