PROBLEM TO BE SOLVED: To provide a method for efficiently and stably manufacturing various kinds of ethylene/vinyl alcohol copolymers (EVOH's) each in a small quantity so as to cope with diversification of uses of the EVOH's. SOLUTION: An EVOH (component A) having a water content of 5-40 wt.% extruded from a first extruder and an additive component (component B) are introduced into a second extruder, molten and kneaded and then delivered. Another component (component C) can be further introduced into the first extruder. |
