Abstract:
1. An additive mixture for fuels or lubricants, containing at least one compound a formula I optionally in combination with one or more further fuel or lubricant additives, said formula I being where R B is a benzene ring which may additionally carry 4—(m+n) substituents which differ from R A is C m and n, independently of one another, are 0 or 1, p is an integer from 5 to 200 and the radical (R a R b m R c n )B— has a number average molecular weight of from 254 to 5000, which is obtained by a process comprising the steps of a) alkylating a phenol of the formula H—B—OH with at least one polyolefin the presence of an alkylation catalyst and either b1) alkoxylating the product obtained in (a) by reacting it with at least one compound which is selected from C b2) etherifying the product obtained in (a) with a polyalkylene oxide of the formula H—(O—A) and in which the step (a) is carried out at a temperature of from −10° C. to 50° C. and with a Lewis acid or a protic acid as alkylation catalyst.
