METHOD FOR PREPARING ETHYLENE-VINYL ACETATE WITH LOW MELT INDEX

摘要

The present invention relates to a method for preparing an ethylene-vinyl acetate (EVA) having a melt index of 10 g/10min or less that includes: applying an electron beam with an exposure dose of 1 to 25 kGy to an ethylene-vinyl acetate resin composition including an ethylene-vinyl acetate resin having a vinyl acetate content of 15 to 50 wt%. The ethylene-vinyl acetate prepared has a high vinyl acetate content to secure good properties with regard to transparency, elasticity, or the like, consequently having high processability and good mechanical properties such as a low melt index and thus can be applied to various industrial uses.
