The invention discloses a microreactor system, a method for preparing a polymer by using the microreactor system and application of EVA (Ethylene Vinyl Acetate). The micro-reactor system comprises a first conveying unit, a second conveying unit, a micro-mixer unit and a micro-tube reactor unit, the first conveying unit and the second conveying unit are both connected with the micro-mixer unit, the micro-mixer unit is connected with the micro-tube reactor unit, and the micro-tube reactor unit is connected with the micro-mixer unit. And at least one of the first conveying unit and the second conveying unit conveys reaction raw materials to the micro-mixer unit. Therefore, the micro-reactor system can be used for preparing polymers such as polyvinyl acetate and EVA (Ethylene Vinyl Acetate), and the micro-tube reactor unit can eliminate a gasification space in the preparation process, so that a gas phase and a liquid phase are not easy to appear in the reaction process, and the uniform and rapid polymerization re
