This invention relates to easily conveyable and easily meterable mixtures having high stability in storage, containing aromatic mineral oils and phenylenediamines, the content of phenylenediamines in the mixture being 1 to 99 wt. %. The mixtures of mineral oils and phenylenediamines according to the invention are used in the production of rubbers and rubber articles.

Easily transportable and meterable mixtures of aromatic oils and

Phenolic resins obtained by condensation from alkylphenol, aldehyde, polyamine and polyether in a molar ratio of 1:0.7 to 1.3:0.005 to 0.2:0.001 to 0.3 are suitable as tackifiers for rubber mixtures.

Phenolic resins using polyamines and polyethers in their production

Diaryl guanidines can be obtained in a high degree of purity and in high yields from the crude melt obtained from the reaction of arylamines and cyanogen chloride by dissolving the hot melt in water, extracting this solution with a mixture of at least one water insoluble, apolar hydrocarbon and at least one polar organic compound and precipitating the diaryl guanidine from the purified, aqueous solution by the addition of alkali metal hydroxide.

Process for the isolation of diaryl guanidines

The present invention relates to new benzylidenemalonic or vinylogous benzylidenemalonic acid polyesters containing structural units of the formula (I) ##STR1## their preparation and their use for the UV stabilization of thermoplastics, preferably thermoplastic, aromatic polycarbonates, thermoplastic, aromatic polyesters or thermoplastic polymethylmethacrylates.

The light fastness of polyamide dyeings can be improved by treating polyamide fibre materials, before, during or after dyeing, with copper complexes of the reaction products of salicylaldehydes with amines (for example cyclohexylamine), or with copper complexes of o-hydroxybenzophenones.

Process for improving the light fastness of polyamide dyeings with

The invention concerns agents for protecting the skin against UV-radiation, said agents comprising an oil or wax having dissolved therein a compound of the formula ##STR1## in which R is an n-hexyl, n-octyl or n-decyl radical or a primary isoalkyl radical with 9 or 10 carbon atoms.
