Publication number: 20100273910Abstract: The present invention relates to polyfunctional nitrones (optionally in the form of nitrone-terminated polymers) and to their use as crosslinking agents and matting agents, preferably for producing stable molding compounds, knifing fillers, and use thereof in inks, coatings, and adhesives. Low crosslinking temperatures characterize the invention. Through the use of polyfunctional nitrones it is possible for all unsaturated polymers to be cured, solidified and/or structured at low temperatures, preferably without use of a catalyst. Depending on the amount of nitrone-terminated polymers and/or low molecular mass polyfunctional nitrone used it is possible to exert a strong influence over the optical and the mechanical properties of the coated surfaces. By optical properties are meant, among others, the gloss of the coating systems and the surface structuring, e.g., the matt effect.Type: ApplicationFiled: December 10, 2008Publication date: October 28, 2010Applicant: HEINRICH-HEINE-UNIVERSITÄTInventors: Hakan Cinar, Helmut Ritter

Patent number: 7820765Abstract: A functionalized polymer includes a polymer chain and, bonded thereto, an functional group having the general formula —NHAR1 where A is an oxygen atom, a sulfinyl (thionyl) group, a sulfonyl group, a quaternary phosphonium group, or a secondary amino group and where R1 is a hydrogen atom or a moiety of the general formula —CH2Z where Z is H or a substituted or unsubstituted aryl, alkyl, alkenyl, alkenaryl, aralkenyl, alkaryl, or aralkyl group. The material can be the reaction product of a living polymer and a compound that includes protected imine functionality. The functional group can interact with particulate filler such as, e.g., carbon black.Type: GrantFiled: July 19, 2006Date of Patent: October 26, 2010Assignee: Bridgestone CorporationInventor: Yuan-Yong Yan

Patent number: 7750087Abstract: A method for preparing a functionalized polymer comprising the steps of preparing a pseudo-living polymer by polymerizing conjugated diene monomer with a lanthanide-based catalyst, and reacting the pseudo-living polymer with at least one functionalizing agent defined by the formula (I) where A is a substituent that will undergo an addition reaction with a pseudo-living polymer, R1 is a divalent organic group, R2 is a monovalent organic group, and each R4, which may be the same or different, is a monovalent organic group or a substituent defined by —OR5 where R5 is a monovalent organic group, with the proviso that A, R1, R2, R4, and R5 are substituents that will not protonate a pseudo-living polymer. Also, the functionalized polymer and a vulcanizable composition containing the polymer.Type: GrantFiled: October 6, 2005Date of Patent: July 6, 2010Assignee: Bridgestone CorporationInventors: Yoichi Ozawa, H.
