Research Progress on Modification of Ethylene Ainyl Acetate Copolymers
Ethylene vinyl acetate copolymer(EVA)has excellent flexibility,corrosion resistance,processability,non-toxicity,and environmental friendliness.It is widely used in various fields such as films,hot melt adhesives,adhesives,wire,and cable.However,EVA has disadvantages such as low viscosity,and poor thermal and mechanical properties,which limit its development and applications.Therefore,the preparation of new modified EVA materials with excellent performance has become a research hotspot in recent years.This review summarizes the research progress on different modification methods of EVA,focuses on both chemical and physical modification,analyzes the advantages and disadvantages of different modification methods,and finally looks forward to EVA modification methods and research directions.
