摘要:
The present invention discloses a hot drawn multilayered structure comprising a layer of an ethylene-vinyl alcohol copolymer composition comprising 70 to 95 wt% of EVOH having an ethylene content of 25 to 60 mol% and a saponification degree of at least 90% and 5 to 30 wt% of an aliphatic copolymer polyamide containing capramide as a main structural unit, the ratio of the number of methylene groups to the number of amide groups satisfying the equation: having a melting point of 110 to 180°C and showing a melt index of 0.1 to 10 g/10 min, and a thermoplastic resin layer provided on at least one surface of said layer. The multilayered structure of the present invention has excellent and highly uniform gas barrier properties and contains hardly any gel or hard spots.

摘要:
A laminated structure comprising a base material made of a polyvinyl chloride resin, polystyrene resin, polyacrylic resin, polycarbonate resin or polyamide resin; having provided on at least one surface thereof a layer of a blend of a polyesteramide and an EVOH. In this laminated structure the base material layer and the EVOH layer adhere firmly to each other. The structure is excellent in gas barrier properties, prevention of plasticizer bleeding and soil prevention, and is useful as wall paper, portfolio, desk mat, etc.
摘要:
Described are resin compositions containing a saponified product of a modified ethylene-vinyl acetate copolymer containing 0.1 to 10 mole percent of pyrrolidone ring containing units and shaped articles prepared from this composition, especially a multilayered structure formed by a high speed thermal drawing, having excellent uniform gas barrier properties without pinholes, cracks and localized uneven stretching.
