Abstract
A method for producing propylene polymers having a broad molecular weight distribution (MWD) is disclosed. The method uses a Ziegler catalyst and one silane donor. The silane donor is selected from vinyltrimethoxysilane or dicyclohexyldimethoxysilane. The polymers made by the method have an MWD greater than or equal to 7.0.
