    Abstract: Fuels for spark ignition engines, which fuels contain small amounts of a polyether amine and/or polyether amine derivative of the general formula … … in which R is a phenol- or alkylphenol-polyether radical of the general formula … … or a cyclohexyl- or alkylcyclohexyl-polyether radical of the general formula … … R and R may be identical or different and are hydrogen, the phenol- or alkylphenol-polyether radical (IIIa), the cyclohexyl- or alkylcyclohexyl-polyether radical (IIIb), the acyl radical of a carboxylic acid having 2 to 24 carbon atoms or the hydroxyalkyl radical of the general formula … … or R is an alkyl radical having 1 to 20 carbon atoms and R is hydrogen, the phenol- or alkylphenol-polyether radical (IIIa), the cyclohexyl- or alkylcyclohexyl-polyether radical (IIIb), the acyl radical of a carboxylic acid having 2 to 24 carbon atoms or the hydroxyalkyl radical (IV), R is the carboxylate radical of a carboxylic acid having 2 to 24 carbon atoms, R , R and R may be identical or different and are hydrogen or a hydrocarbon radical having 1 to 30 carbon atoms, R is a polyether chain comprising alkene oxides having 2 to 8 carbon atoms or mixtures of these alkene oxides having 2 to 100 alkene oxide units in the chain, and R is hydrogen or a hydrocarbon radical having 1 to 6 carbon atoms, and m is the numbers 0 to 5, the mean molecular weight Mn of the polyether amines or polyether amine derivatives (I) or (II) being 500 to 8000, and the polyether amines or the parent polyether amines to the polyether amine derivatives being prepared by amination of phenol- or alkylphenol-polyethers of the general formula … … or of cyclohexyl- or alkylcyclohexyl-polyethers of the general formula … … in which R , R , R and R are as defined above, using ammonia or primary amines. … The novel polyether amines and their derivatives have an improved valve-cleaning action.

    Abstract: Polymers Ia and Ib carrying functional groups, obtainable by A) 1. hydrogenation of the olefinic double bonds of a polymer IIa comprising a) from 20 to 100% by weight of a conjugated diene, b) from 0 to 80% by weight of a vinylaromatic compound and c) from 0 to 20% by weight of further comonomers, to give the hydrogenated polymers IIb, 2. metallation of IIb using an organoalkali metal compound to give IIc, 3. reaction of IIc with a diaziridine III to give IId and 4. hydrolysis or alcoholysis of IId to give Ia, or by B) 1. partial hydrogenation of IIa to give partially hydrogenated polymers IIb', 2. epoxidation of the double bonds of IIb' to give IIe and 3. reaction of IIe with a compound IV carrying functional groups to give Ib. These polymers Ia and Ib are suitable as viscosity index improvers for engine oils.
