Patent number: 8163851Abstract: The invention provides a polymeric salt, wherein the monomer unit of the polymeric salt comprises two nitrogen containing heterocyclic groups joined by a rigid linker group. The nitrogen atoms of the heterocyclic groups are disposed so as to enable a polymeric carbene formed by from the polymeric salt to complex with a metal atom. The invention also provides a polymeric metal complex which may be made from the polymeric salt, and which may be used in a Suzuki coupling reaction. The polymeric salt may be used as a heterogeneous organic catalyst for cyanation reaction.Type: GrantFiled: July 5, 2006Date of Patent: April 24, 2012Assignee: Institute of Bioengineering and NanotechnologyInventors: Jackie Y. Ying, Yugen Zhang, Dingyu Hu, Paranab K. Patra

Publication number: 20120095162Abstract: The present invention relates to a process for preparing high-functionality polyethers having a Hazen color number of less than 500, by converting tris(hydroxyethyl) isocyanurate (THEIC) and one or more difunctional alcohols and/or modifying reagents with the aid of acidic catalysts. The present invention further relates to high-functionality polyethers having a color number of less than 10, obtainable by such a process, and to the use of these high-functionality polyethers as adhesion promoters, thixotropic agents, rheology modifiers of polymers, in printing inks, paints and coatings, or as units for preparation of polyaddition or polycondensation polymers.Type: ApplicationFiled: October 14, 2011Publication date: April 19, 2012Applicant: BASF SEInventors: Bernd BRUCHMANN, Anna Cristadoro, Oihana Elizalde, Angelika Maria Steinbrecher, Monika Haberecht
