Abstract:

Textile and fibrous materials were irradiated in oxygen, nitrogen, and vacua of 0.05 mm and 0.000001 mm. Deterioration of all hydrogen-containing polymers is faster when irradiated in oxygen than when irradiated in nitrogen or in a vacuum. Unlike the other polymers studied, the experimental polymer HT-1 deteriorates more rapidly when irradiated with 369 millimicrons ultraviolet than when irradiated with 244 millimicrons or 314 millimicrons ultraviolet. Fiberglas and fused silica are unaffected by ultraviolet. Author
