Title:
ETHYLENE - VINYL ESTER-BASED COPOLYMER SAPONIFICATION PRODUCT COMPOSITION AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/088862
Kind Code:
A1
Abstract:
Provided are: an EVOH resin composition having excellent inorganic compound dispersion characteristics; and an EVOH resin composition production method having excellent productivity and excellent inorganic compound dispersion characteristics. This EVOH resin composition contains an EVOH resin (A) and an inorganic compound (B) and has a crystallinity of at least 36%. This EVOH resin composition is obtained by: inserting an EVOH resin (A), an inorganic compound (B), and water (C) into a kneading device comprising a screw-type side feeder 3; driving the screw-type side feeder 3 and melting and kneading the EVOH resin, inorganic compound and water; then discharging water vapor from the screw-type side feeder 3 while suppressing leakage of the EVOH resin composition from the screw-type side feeder 3, and making the water content to less than 5 wt%.
