Document Type and Number:
WIPO Patent Application WO/2017/078103
Kind Code:
A1
Abstract:
Provided is a resin composition which comprises an isobutylene-based copolymer (A) having halogen atoms, an ethylene/vinyl alcohol copolymer (B), and a halogen-trapping agent (C), wherein the mass ratio of the ethylene/vinyl alcohol copolymer (B) to the isobutylene-based copolymer (A) having halogen atoms, (B)/(A), is 20/80 to 50/50 and the halogen-trapping agent (C) is contained in an amount of 0.01-1 part by mass per 100 parts by mass of the sum of the isobutylene-based copolymer (A) having halogen atoms and the ethylene/vinyl alcohol copolymer (B). This resin composition is excellent in terms of gas-barrier property and flexibility and renders long-term stable production possible.
