摘　　要：如何利用高分子物理理论知识解决生产相关的工程问题是现实应用中存在的一个难题。乙烯-醋酸乙烯酯(EVA)共聚高分子是以醋酸乙烯酯和乙烯为单体通过自由基聚合而成的一种高分子,EVA共聚物的合成、分子结构和工程应用涉及高分子物理中的高分子的链结构、聚集态行为、高分子链运动和高分子溶液等内容。围绕EVA共聚物的理论解析,本文主要参考高分子物理教材的编写顺序针对EVA共聚物的近程结构、结晶、玻璃化转变温度和反应过程的高分子溶液状态等内容进行解析。通过相关高分子物理知识的理论解析有效提升对EVA共聚物应用场景的理解及改性认知深度。It is a challenging task in practical application to apply the theoretical knowledge of polymer physics to solve engineering problems related to production.Ethylene-vinyl acetate(EVA)copolymer is synthesized through free radical polymerization of vinyl acetate and ethylene as monomers.The synthesis,molecular structure,and engineering application of EVA copolymer involve polymer chain structure,aggregation behavior,polymer chain movement,and polymer solution properties in the field of polymer physics.The paper mainly refers to the preparation sequence of polymer physics textbooks to analyze the short-range structure,crystallization,glass transition temperature,and polymer solution state of EVA copolymer during the reaction process.Through a theoretical analysis of relevant polymer physics knowledge,it effectively improves understanding of application scenarios for EVA copolymers and deepens cognitive modification.
