Walter Kaminsky, Maria Buschermohle: 1-olefin stereoblock polymer, and a process for its preparation. Hoechst Aktiengesellschaft, July 18, 1989: US04849487 (38 worldwide citation)

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 sui ...

A liquid fraction and a gas fraction produced during the reprocessing of waste material containing CH compounds by pyrolysis, have a mass ratio approximately equal to 1. Since the liquid fraction is more suitable for further processing than the gas fraction, there is an incentive to augment the liqu ...
