Abstract
One class of compounds that has been employed as stabilizers in many polyolefin applications is phosphites. In particular trisnonylphenyl phosphite (P-1) and distearyl pentaerythritol diphosphite (P-2) have found widespread usage in these polymers. These two phosphites (see structures in Figure 1) are used in polyolefins to protect them against melt flow and color change during processing; to retard discoloration in end use applications; and to reduce degradation and discoloration due to U.V. exposure. The face that they are FDA sanctioned for use in olefin polymers has also contributed to their success.
