标题 :Triazole- And/Or Triazolium-Based Polymers And Copolymers As Additives For Chemical Mechanical Planarization Slurries
发明人：LARBIG GREGOR; KIRSCH PEER; HENGST MATTHIAS; SHI XIAOBO; STENDER MATTHIAS
权利人:VERSUM MAT US LLC
摘要:Synthesis of triazole- and/or triazolium-based polymers is disclosed. Chemical Mechanical Planarization (CMP) slurries comprise abrasives; activator; oxidizing agent; additive comprising triazole- and/or triazolium-based polymers; and water. The use of the synthesized triazole- and/or triazolium-based polymers in the CMP slurries reduces dishing and erosion in highly selective tungsten slurries.

标 题:Polycationic Polymer Or Copolymer Having Different Cation Types For Slurries In Chemical Mechanical Planarization
发明人：LARBIG GREGOR; SHI XIAOBO
权利人:MERCK PATENT GMBH; VERSUM MAT US LLC
摘要:Synthesis of polycationic polymer or copolymer is disclosed. The polycationic polymer or copolymer are formed by at least one first cationic monomer and at least one second cationic monomer wherein the first cationic monomer and the second cationic monomer have different cationic groups; such as imidazolium group and non-imidazolium group. Chemical Mechanical Planarization (CMP) slurries comprise abrasives; activator; oxidizing agent; additive comprising polycationic polymer or copolymer; and water are also disclosed. The use of the synthesized polycationic polymer or copolymer in the CMP slurries reduces dishing and erosion in highly selective tungsten slurries.

标 题:2-Acylimidazole compounds, their synthesis and use as medicinal agents
发明人：KROEPLIEN UDO; ROSDORFER JOACHIM
权利人:COCA COLA CO
摘要:The 2-acylimidazole compounds have an alkyl or aryl substitution at the 2-position and an alkyl, hydroxyalkyl, polyhydroxyalkyl or aryl substitution at the 4-position. They exhibit an ability to decrease in vivo leucocyte populations and are consequently useful as immunosuppressive medicinal agents for prevention of transplanted tissue rejection, treatment of leukemia and treatment of cell-mediated autoimmune disease.
