Document Type and Number:
Japanese Patent JP5928752
Kind Code:
B2
Abstract:
An object of the present invention is to provide a multilayered pipe having a layer comprising a resin composition containing EVOH, which is unlikely to exhibit the occurrence of cracking in the EVOH layer due to oxidative degeneration and has excellent gas barrier property even during long-term usage at high temperatures, and also to provide a resin composition for obtaining the multilayered pipe. The present invention relates to a resin composition containing 0.001 to 5 parts by mass of an antioxidant (B) and 0.00001 to 0.3 parts by mass of a conjugated polyene compound (C) having a molecular weight of 1000 or less, relative to 100 parts by mass of an ethylene-vinyl alcohol copolymer (A).
