Ethylene-vinyl alcohol polymer compositions and use thereof |
摘要 |
<p>Disclosed is a polymer composition which comprises as the main components an ethylene-vinyl alcohol base copolymer (A) and a block copolymer (B) which has a polymer block containing an aromatic vinyl monomer unit and a polymer block containing an isobutylene unit, and in which a phase composed of said component (A) and a phase composed of said component (B) are separated from each other. This polymer composition has good flexibility or rubber elasticity and also good barrier properties to gases or the like and it can be molded or formed into a product having such properties without a vulcanization step so that it is useful as a material for packaging material for food or drink, container packing, medical container for infusion fluid or the like.</p> |
