Abstract

(Graph Presented) PTDP is coordinated to the aliphatic carbonyl oxygen, as well as to the phthalate oxygens [phthalate oxygen : single carbonyl = 21: 38%], although the interaction of the silver ions with the latter is approximately twice as strong as that with the former. Thus, the weaker interaction between PTDP and the silver ions causes the silver ions to be readily reduced to silver metal, resulting in the loss of carrier activity for olefins and, consequently, poor long-term stability.
