Abstract
Stereoblock polymers of 1-olefins having a broad uni-, bi-, tri- or multimodal molecular weight distribution are obtained when a catalyst which comprises a chiral metallocene containing bridges and an alumoxane is used for the polymerization of the 1-olefins. The polymers are particularly highly suitable for the production of transparent films.
