摘要：

This paper is concerned with the family of ethylene-vinyl acetate copolymers, also called EVA resins, which are used as raw materials for hot melt pressure-sensitive adhesives. In one respect, the EVAs are the very antithesis of the block copolymers that also are used in hot melt pressure-sensitive adhesives. They are, in fact, nearly perfectly random copolymers. Shown is an overall structural formula for copolymers of ethylene and vinyl acetate. Extensive property data are plotted and discussed. It is demonstrated that EVA-based hot melt pressure-sensitives have progressed to the point where they now have performance properties which meet the requirements of many label and some tape applications. It is anticipated that this progress will continue as formulators expand their developmental work in this relatively new hot melt area.
