the first catalyst systems contained ethyl benzoate as internal donor and a second aromatic ester as external donor, but the catalysts most widely used in polypropylene manufacture contain a diester (e.g. diisobutyl phthalate) as internal donor and are used in combination with an alkoxysilane external donor of type rr?si(ome) 2 or rsi(ome) 3.

diisobutyl phthalate lanxess,and if the recommended safe use and handling procedures are followed, diisobutyl phthalate is not expected to pose a significant risk to human health or the environment. references. international chemical safety card, diisobutyl phthalate, international programme on chemical safety (ipcs) iuclid dataset, diisobutyl phthalate (84-69-5)
