  In the method of continuously producing pellets by continuously extruding a saponified ethylene-vinyl acetate (EVOH) solution in a strand form into a coagulation liquid and then cutting the resulting strand, the ratio between the weight X of the coagulation liquid and the weight Y of the strand of the saponified ethylene-vinyl acetate copolymer, namely the ratio X/Y, is set at 50 to 10,000. The coagulation liquid preferably contains 1 to 10,000 ppm of a carboxylic acid, 1 to 50,000 ppm of a carboxylic acid ester, or 1 to 15,000 ppm of a carboxylic acid salt. It is preferred as well that the water content of the continuously produced EVOH pellets be adjusted to 20 to 80% by weight and then brought into contact with an aqueous solution, having a specified concentration, of at least one compound selected from the group consisting of a boron compound (B), an acetic acid salt (C) and a phosphoric acid compound (D). Furthermore, the thus-obtained EVOH pellets are subjected to drying treatment by a combination of stationary drying and fluidized drying.

  在将皂化的乙烯-醋酸乙烯（EVOH）溶液以股状连续挤入凝固液，然后切割所得到的股而连续生产颗粒的方法中，凝固液的重量 X 与皂化的乙烯-醋酸乙烯共聚物股的重量 Y 之比，即 X/Y 之比，设定为 50 至 10000。 凝固液最好含有 1 至 10,000 ppm 的羧酸、1 至 50,000 ppm 的羧酸酯或 1 至 15,000 ppm 的羧酸盐。 最好还能将连续生产的 EVOH 颗粒的含水量调整到 20% 至 80% （按重量计），然后与至少一种选自硼化合物 (B)、乙酸盐 (C) 和磷酸化合物 (D) 的指定浓度的水溶液接触。 此外，通过固定干燥和流化干燥相结合的方法，对由此获得的 EVOH 颗粒进行干燥处理。
