The effect of zinc diisopropyl dithiophosphate (ZnDTP) chelate over the range of to wt.% on the photostabilized degradation of poly(2,6‐dimethyl‐1,4‐phenylene oxide) (PPO) films was examined. The degradation of the polymer was remarkably affected by the concentration of the ZnDTP which acted as photostabilizer at all concentrations.

Un dialkyldithiophosphate de zinc (ZDDP, de l'anglais zinc dialkyldithiophosphate), est un additif pour lubrifiants appartenant à une famille de composés chimiques découverte par la société britannique Castrol et constituée d'un atome de zinc complexé avec deux anions d'acide dialkyldithiophosphorique [P(OR) 2 S 2] –, R indiquant une substitution avec un groupe alkyle.

Zinc dialkyldithiophosphates were originally prepared by the reaction of phosphorus pentasulfide (P 2 S 5) and one or more different alcohols to give the dialkyldithiophosphoric acid, which was neutralized by the addition of zinc oxide to give the product as is shown in Figure 2 . The ability to use a mixture of alcohols, resulting in a statistical mixture of products allows the chemical and physical properties of .
