Hydrous pellets of ethylene-vinyl acetate copolymer hydrolyzate, production thereof and moldings from such hydrous pellets |
摘要 |
The hydrous ethylene-vinyl acetate copolymer hydrolyzate (EVOH) pellets of the present invention are characterized in that they are hydrous pellets of an ethylene-vinyl acetate copolymer hydrolyzate (EVOH) (A) having an ethylene content of 5 to 60 mole percent and a degree of saponification of not less than 90 mole percent and have a water content of 5 to 60% by weight and a storage elastic modulus at 20 DEG C of 2 x 10<6> to 5 x 10<7> Pa. These hydrous pellets preferably contain a small amount of an alcohol (B) containing 1 to 5 carbon atoms and/or a small amount of at least one compound (C) selected from the group consisting of a boron compound (c1), acetic acid (c2), an alkaline metal acetate (c3), an alkaline earth metal acetate (c4) and a phosphoric acid compound (c5). |
