Ethylene-based polymer blends having an MWD of at least about 2 are made in a single reactor using a mixed constrained geometry catalyst (CGC) system. The process comprises the steps of contacting under polymerization conditions and in a single reaction vessel (i) ethylene, (ii) at least one C3-C20 (-olefin,...http://www.google.de/patents/US6369176?utm_source=gb-gplus-sharePatent US6369176 - Process for preparing in a single reactor polymer blends having a broad molecular weight distribution
