20080274924 | METHOD FOR PRODUCING MANNICH ADDUCTS THAT CONTAIN POLYISOBUTYLENE PHENOL - Polyisobutenylphenol-containing Mannich adducts are prepared by | 11-06-2008 |
20100004427 | METHOD FOR THE REMOVAL OF ISOBUTENE OLIGOMERS FROM AN ISOBUTENE POLYMER - A process is described for removing isobutene oligomers from an isobutene polymer by stripping the isobutene polymer with vapors of a saturated hydrocarbon having at least 8 carbon atoms and at least partly driving out the isobutene oligomers. Troublesome isobutene oligomers are substantially removed without impairing the reactivity of the isobutene polymer (expressed as the content of the methylidene double bonds). | 01-07-2010 |
20100234542 | PREPARATION OF REACTIVE, ESSENTIALLY HALOGEN-FREE POLYISOBUTENES FROM C4-HYDROCARBON MIXTURES WHICH ARE LOW IN ISOBUTENE - The present invention relates to a process for preparing reactive and essentially halogen-free, especially fluorine-free, polyisobutenes from low-isobutene C | 09-16-2010 |
20100292422 | METHOD FOR PRODUCING COPOLYMERS MADE FROM ISOBUTENE AND AT LEAST ONE VINYLAROMATIC COMPONENT - The invention relates to a method for producing copolymers made from isobutene and at least one vinylaromatic component. Said method consists of polymerising isobutene or a hydrocarbon mixture containing isobutene with at least one vinylaromatic compound in the presence of a solvent-stable transistion metal complex comprising slightly co-ordinating anions as a polymerisation catalyst. The invention also relates to copolymers made of isobutene and at least one vinylaromatic compound, which can be obtained by means of said inventive method, in addition to specific functionalisation products therefrom. | 11-18-2010 |
20110034360 | ALPHA-OLEFIN/ISOBUTENE DIBLOCK COPOLYMERS - The present invention relates to diblock copolymers of the formula A-B which are formed from a polymer block A which is formed essentially from α-olefin units having from 6 to 22 carbon atoms, and a polymer block B which is formed essentially from isobutene units, to a process for their preparation, to their use in lubricant compositions and to lubricant compositions which comprise such diblock copolymers. | 02-10-2011 |
20110113678 | USE OF POLYNUCLEAR PHENOLIC COMPOUNDS AS STABILISERS - The use of polycyclic phenolic compounds which have up to 20 benzene rings per molecule and are obtainable by reacting a tetrahydrobenzoxazine I | 05-19-2011 |
20110251114 | METHOD FOR PRODUCING MANNICH ADDUCTS THAT CONTAIN POLYISOBUTYLENE PHENOL - Polyisobutenylphenol-containing Mannich adducts are prepared by | 10-13-2011 |
20140163224 | USE OF TETRAHYDROBENZOXAZINES AS STABILISERS - The use of tetrahydrobenzoxazines I | 06-12-2014 |
