Zusammenfassung:	External donor systems, catalyst systems and olefin polymerization processes are described herein. The external donor systems generally include a first external donor represented by the general formula SiR2m(OR3)4-m, wherein each R2 is independently selected from alkyls, cycloalkyls, aryls and vinyls, each R3 is independently selected from alkyls and m is from 0 to 4. The external donor systems further include a second external donor represented by the general formula SiR4 m( L'invention concerne des systèmes de donneurs externes, des systèmes de catalyseur et des procédés de polymérisation d'oléfine. Les systèmes de donneurs externes comprennent généralement un premier donneur externe représenté par la formule générale SiR2m(OR3)4-m, où chaque R2 est indépendamment choisi parmi les alkyles, cycloalkyles, aryles et vinyles, chaque R3 est indépendamment choisi parmi les alkyles et m vaut 0 à 4. Les systèmes de donneurs externes comprennent en outre un second donneur externe représenté par la formule générale SiR4 m(
