Mixtures of at least one amine, polyamine or alkanolamine and at least one polyetheramine and their use as additives for gasoline engine fuels.

Mixtures suitable as fuel additives

Poly-1-n-alkenylamines, and fuel and lubricant compositions containing

Halogen-free fuel additives based on a long-chain hydrocarbon having a polar terminal group are obtained by reacting a hydroformylated olefin with a polyamine and hydrogenating the reaction product.

Fine-celled foams are produced by a process in which a styrene polymer is melted, the melt is mixed with a volatile blowing agent and a nucleating agent under superatmospheric pressure, the mixture is let down to atmospheric pressure, and the foam is cooled. The nucleating agent employed comprises from 0.02 to 2% by weight of the calcium salt of a long-chain fatty acid, and from 0.01 to 1% by weight of a finely divided, inorganic substance which is insoluble in the styrene polymer, a mixture of calcium stearate and magnesium oxide being preferred.

Production of fine-celled foams from styrene polymers

A process and associated apparatus for filling packages with free-flowing solids through spouts, in which some of the material is initially fed to the package with the latter in its gravity position, the position of the package is changed once or a number of times with shaking of the entire package, and finally the remainder of the material is filled into the package with the latter in its gravity position.
