説明

<jats:title>Abstract</jats:title><jats:p>The chemistry of the catalyst‐cocatalyst interaction was investigated in systems containing different internal/external donor pairs. Qualitatively similar results were obtained with the ethyl benzoate/methyl <jats:italic>p</jats:italic>‐toluate (EB/MPT) and dibutyl phthalate/triethoxy(phenyl)silane (DBP/EPS) systems, which thus were assumed to follow the same model. Quantitative differences were accounted for by assuming a different basic strength of the two donor pairs towards MgCl<jats:sub>2</jats:sub> and AlEt<jats:sub>3</jats:sub>.</jats:p>
