“…This difference in topology as a function of reactor type is a known difference between autoclave and tubular reactor units. Commercially, autoclave reactors tend to be restricted to use in cases where higher amounts of comonomer are desired as they tend to be less efficient relative to tubular reactors. While the process type is one way to control topology of the resultant EVA polymer, the target melt flow and vinyl acetate content also influence the degree of LCB in the resultant polymer.…”

Cross-linked ethylene–vinyl acetate (EVA) is used in technically demanding applications ranging from solar cell encapsulants exposed to years of harsh environments to athletic shoes exposed to countless impact recovery cycles. The thermomechanical properties of this versatile material represent the combined responses of semicrystalline and elastomeric components. To fully describe structure–property relations of cross-linked EVA, it is necessary to explore the combined effects of vinyl acetate content, molecular weight, and chain topology on the thermomechanical properties. The interdependent effects of these factors influence both the amount of crystallinity and the size of the crystallites within the material. Subsequent cross-linking of EVA reduces crystallinity relative to the un-cross-linked starting materials. By controlling the properties of the un-cross-linked starting materials and the degree of cross-linking, it is possible to tune the performance properties of the cross-linked EVA. Understanding these effects enables material selection and property adjustment to meet the demands of existing and emerging applications.
