Abstract:
The invention relates to a solvent-stable metal catalyst having slightly co-ordinating counter anions of formula I [M(L) a (Z) b ] m+ m(A - ) (I), wherein M represents a transition metal of groups 3 - 12 of the periodic system, a lanthanide or a metal of groups 2 or 13 of the periodic system; L represents a solvent molecule; Z represents a mono or polycharged ligand; A - represents a slightly or non co-ordinated anion; a represents a whole number which is greater than or equal to 1; b represents a whole number which is greater than or equal to 1, whereby the total from a and b is between 4 and 8, and m represents a whole number from 1 6. The invention also relates to a method for polymerising olefinically unsaturated compounds in the presence of said catalyst and copolymers which are made of monomers comprising isobutene and at least one vinylaromatic compound which is obtained according to said inventive method.

The present invention relates to the use of polyamines having at least one terminal secondary or tertiary amine function as a detergent additive for fuels and lubricants; to additive concentrates comprising such polyamines; to fuels and lubricants additized with these polyamines and to processes for their preparation.
Abstract:
New block copolymers (I) comprise a polyisobutenyl-succinic acid mono-esterified with a (co)polyalkylene oxide monoalkyl or monoaryl ether (i.e. a lipophilic polyisobutene block bonded to a hydrophilic polyoxyalkylene block via a succinic acid linker). Polyisobutenyl-succinic acid derivatives of formula (I) are new. [Image] L : polyisobutenyl group of number average molecular weight (Mn) 200-20000; M+>H+> or an equivalent of alkali(ne earth) metal, ammonium or mono- or polyalkylammonium ion; R : group formed from oxyethylene, oxypropylene and/or oxybutylene units; A : methyl, ethyl, propyl, butyl or aryl (optionally substituted). An independent claim is included for the preparation of the above copolymers.
Abstract:
Additive mixture comprises a silicone antifoam and a lubricity improver selected from (partially) neutralized fatty acids and long-chain carboxylic acids and their esters. Independent claims are included for: (1) fuel composition comprising a hydrocarbon fuel, an additive mixture as above and optionally another additive; (2) additive concentrate comprising an additive mixture as above, a diluent and optionally another additive.
