Poly aryl ether ketonejs

Other compounds are triphenyl phosphate and substituted derivates, such as tricresyl phosphate. However, it has been objected that, due to their high vapor pressure, these compounds might escape from the melt at the processing temperature customary for poly(aryl ether ketonejs, which can lead to odor nuisance and, in the case of injection molding, to coatings forming on the mold surface. For this reason, less volatile stabilizers have been proposed. ... 

The phosphonite type is much less effective than the phosphite type in the stabilization of poly(aryl ether ketonejs. However, the addition of organic phosphorus compounds in conjunction with an organic acid, such as oxalic acid or acetic acid results in a very significant reduction in melt viscosity, even where the phosphorus compound alone has a detrimental effect. The results using the stabilizers can be summarized as follows ...
