Thermal and Oxidative Stability. In general, polyolefins undergo thermal transitions at much lower temperatures than condensation polymers thus, the thermal and oxidative stability of polyolefin fibers are comparatively poor. Preferred stabilizers are highly substituted phenols such as Cyanox 1790 and lrganox 1010, or phosphites such as Ultranox 626 and Irgafos 168. 

Stabilizers. Preliminary set The stabilizing additives used are listed in Table I. A preliminary set of fabrics was prepared for evaluation which consisted of Good-rite 3125 in two concentrations (a hindered phenol suggested for use on polyamides in B.F. Goodrich Co. Technical Bulletin GC-60, 1982), Cyanox 1790 (hindered phenol),... 

Set A A second set of examples, identified as Set A, was then prepared for a complete evaluation. As listed in Table III, stabilizers applied to Set A were Good-rite 2135, Cyanox 1790,... 

Cyasorb 531, Chimassorb 944LD, Irganox 1098 and Cyanox STDP. Wei To 2 was eliminated from this set because a precipitate remained on the surface of the fabric after it was applied in the preliminary set the precipitate probably was caused by the unusually high add-on. 

The Good-rite 3125 was also combined with the Chimassorb 944LD and Cyanox STDP to evaluate possible synergistic effects between combinations of a hindered phenol stabilizer with first a thioester and then a hindered amine light stabilizer (HALS).

Compound II. This compound is also a hindered phenol antioxidant (Cyanox 1790, American Cyanamid). Compound II is insoluble in water but has a solubility of 4.6 g/100 mL of ethanol. A saturated solution of this compound in ethanol was prepared, and the fabric pieces were immersed in this solution for 30 min. The samples were then dried in the same manner described in the preceding section. The average add-on was 9%.
