Ultraviolet irradiation of plastics. I. Degradation of physical properties

Abstract: Polyethylene, Teflon, nylon, Mylar, and Acrilan have been irradiated in vacuo and in an atmosphere of nitrogen with narrow bands of ultraviolet radiation centered at 244, 314, and 369 μ and with monochromatic ultraviolet light of wavelength 253.7 μ. The physical properties of all these polymers are ultimately degraded by ultraviolet light of any of these wavelengths, but the shorter wavelengths are much the more effective in producing changes. The degradation of polyethylene, nylon, Mylar, and Acrilan is faste… Show more

“…Yellowing is probably due to pyrrole formation during photodegradation or thermal degradation. Stephenson, Moses, and Wilcox [23] compared photodegradation of nylon 66 in nitrogen and in a vacuum. The extent of degradation was greater in nitrogen than in the vacuum.…”

“…Photosensitizers include the degradation products created during melt spinning and high temperature fiber processing, TiO 2 (the standard fiber delusterant), iron salt contamination, as well as certain dyes and dye bath chemicals. The chemistry of the photodegradation of nylon is as complex as thermal degradation and has also been studied extensively (49,(51)(52)(53). Nylon-6 and nylon-6,6 fibers degrade when exposed directly to sunlight outdoors and under glass or to a source of uv radiation in the 300-to 400-nm wavelength range, resulting in the formation of hydroperoxides, chain scission, yellowing, and strength loss (53).…”
