ABSTRACT:
The melt index is reduced and the rheology is modified in ethylene-vinyl acetate copolymers used in the manufacture of films, by the addition of a crosslinking agent to the copolymer. This allows the use of more readily available raw materials and improves the stability of the bubble during stretching of tubular films.
