Abstract:
A container comprised of a laminate having (I) a layer comprising a thermoplastic cycloolefin resin and (II) a layer comprising a resin other than the thermoplastic cycloolefin resin, characterized in that said thermoplastic cycloolefin resin comprises at least 50 to 100% by weight of repeating units (A) having an alicyclic structure, at least 30% by weight of which is repeating units (A-i) having an alicyclic structure other than a norbornane structure; and said thermoplastic cycloolefin resin is a norbornene polymer or a hydrogenation product thereof, wherein said norbornene polymer contains 30% to 100% by weight, based on the total repeating structure units derived from at least one monomer selected from the group consisting of norbornene monomers having two rings and norbornene monomers having at least three rings and is prepared by a ring-opening polymerization of said at least one monomer; and said resin other than the thermoplastic cycloolefin resin is at least one resin selected from the group consisting of chain polyolefins.
