Latest Patents

Rachwalsky's latest patents include a process for preparing isobutene homopolymers or copolymers. This innovative method involves the polymerization of isobutene or an isobutene-comprising monomer mixture in the presence of a Lewis acid or a complex comprising a Lewis acid as a polymerization catalyst. The polymerization is conducted in the presence of at least one hemiacetal or full acetal, which can be obtained through a protic acid-catalyzed reaction of a C-C-hydrocarbyl alcohol with an aldehyde or ketone containing 1 to 12 carbon atoms. Another significant patent is a method for producing polyisobutene, which involves polymerizing isobutene using an inert diluent and a halogen-containing Lewis acid as a catalyst. In this process, the isobutene is introduced in the form of droplets and is contacted with the Lewis acid in a specialized polymerization apparatus.
