Ethylene-vinyl alcohol copolymers wherein ethylene content is 10-70 mol % diad syndiotacticity is not less than 55 mol %, and intrinsic viscosity [η] is not less than 0.05 l/g when measured with a mixed solvent of 85 weight % of phenol and 15 weight % of water at 30 20 C., which show less decrease of resistance to gas permeation under high temperature and high humidity, while retaining resistance to get permeation under low humidity, transparency and melt moldability, and moldings and laminates formed thereof. |
