Thermoplastic polymer composition having barrier properties, sheet or film, laminate structure, packaging material, container and packing for a container |
摘要 |
<p>The present invention provides a thermoplastic polymer composition which is obtained through dynamic vulcanization performed by mixing an ethylene-vinyl alcohol copolymer (I), a modified block copolymer (II) which comprises an aromatic vinyl polymer block and a conjugated diene polymer block and which has a functional group consisting of a carboxyl group and/or its derivative, and an amine crosslinking agent (III), wherein the ethylene-vinyl alcohol copolymer (I) has an ethylene content of from 10 to 60 mole% and has a melt flow rate of from 1 to 20 g/10 minutes, and the amount of the functional group consisting of a carboxyl group and/or its derivative which the modified block copolymer (II) has is from 2 to 20 groups per molecule. The thermoplastic polymer composition is excellent in both barrier properties to gases, organic liquids and the like and flexibility.</p> |
