摘要: The influence of molecular weight and annealing, or heat setting, temperature on the crystallinity subsequent resistance to oxygen permeability was evaluated for biaxially oriented films poly(ethylene terephthalate). Within range investigated, affected amount developed at a given temperature, yet had little permeability. Annealing more directly influenced than did absolute crystallinity.
