TīmeklisAn important assumption in the slope-ratio method is that the complexation reaction continues to completion in the presence of a sufficiently large excess of metal or … TīmeklisOn exposure to UV radiation, polyethylene terephthalate fibers tend to lose their elasticity, elongation, and tensile strength. Polyester films discolor, show surface crazing, and become brittle. UV protection is therefore required in applications sensitive to UV radiation. Polybutylene terephthalate easily absorbs UV radiation below 300nm.
