Abstract: The present disclosure relates to metallocene catalyst and the use thereof to make polyolefins. In particular, the present disclosure relates to silyl-functionalized metallocene catalyst and the use of the silyl-functionalized metallocene catalyst to polymerize olefins and yield a polyolefin. Also, the present disclosure relates to a method for producing a polyolefin comprising at least the step of contacting an olefin with a metallocene catalyst to produce a polyolefin. In particular, the present disclosure provides a method for producing a polyolefin comprising the step of contacting an olefin with a silyl-functionalized metallocene catalyst.
