    • The present invention provides a process for producing pellet of EVOH comprising the steps of introducing an EVOH solution containing alcohol into an apparatus, contacting the solution with water in the apparatus to let out the alcohol with water and then letting out an EVOH hydrous composition from the above-mentioned apparatus (step 1); cutting the EVOH hydrous composition let out therefrom to obtain EVOH hydrous composition pellets (step 2); introducing the obtained EVOH hydrous composition pellets into a dryer to reduce a water content thereof (step 3); melt-kneading the pellets, whose water content is reduced, in an extruder (step 4); and cutting EVOH discharged from the extruder to obtain the pellet of EVOH (step 5). Thus, the EVOH hydrous composition obtained by removing alcohol without deteriorating the environment can be efficiently dried, and pellets having less thermal degradation in drying and a uniform shape can be obtained.
    • 本发明提供了一种制备EVOH颗粒的方法,包括以下步骤:将含有醇的EVOH溶液引入设备中,使该溶液与设备中的水接触,以便用水排出酒精,然后从其中提取出EVOH含水组合物 上述装置(步骤1); 从中排出EVOH含水组合物,得到EVOH含水组合物颗粒(步骤2); 将获得的EVOH含水组合物颗粒引入干燥器中以降低其含水量(步骤3); 在挤出机中熔融捏合含水量降低的颗粒(步骤4); 并从挤出机中排出EVOH以获得EVOH颗粒(步骤5)。 因此,可以有效地干燥除去醇而不使环境恶化得到的EVOH含水组合物,并且可以获得干燥热降低和均匀形状的颗粒。
