METHOD FOR DRYING SAPONIFIED ETHYLENE/VINYL ACETATE COPOLYMER PELLETS

摘要

PROBLEM TO BE SOLVED: To provide a method for drying saponified ethylene/vinyl acetate copolymer pellets reduced in the fluctuations of torque or change in injection amt. at a time of melt molding and capable of obtaining a molded article such as a film or a sheet excellent in thickness uniformity. SOLUTION: An alcohol soln. of a saponified ethylene/vinyl acetate copolymer or an alcohol/water mixed soln. thereof is molded into a strand and this strand is cut to obtain pellets and, when these pellets are dried, static drying and fluidizing drying are combined to be used.
