Latest Patents
Weber's latest patents include innovative advancements in polyethylene moulding compounds. One of his key inventions is a novel Phillips catalyst for the copolymerization of ethylene with α-olefins. This catalyst contains a finely divided, aluminum silicate-supported, phosphorus-containing chromium catalyst. The preparation process involves applying organic phosphorus compounds and chromium compounds to an aluminum silicate hydrogel or xerogel, resulting in a catalyst intermediate that is activated at elevated temperatures in an oxidizing atmosphere. This novel catalyst produces ethylene/α-olefin copolymers with a more uniform distribution of comonomers over the copolymer chains compared to those made with conventional Phillips catalysts. The resulting mouldings exhibit high environmental stress cracking resistance and excellent creep rupture strength.
