摘要: The present invention relates to epoxide resins containing phenol groups and to homo-oligomers thereof of the structure ##STR1## that are obtained by reacting phenolcarboxylic acids with one epoxide equivalent of a polyepoxide. The new compounds are difficultly volatile and resistant to migration and can be used as stabilizers in synthetic polymers, in particular in poly-.alpha.-olefins.

摘要: Copolymer dispersions can be prepared by emulsion polymerization of mixtures of unsaturated carboxylic acids and the esters thereof in the presence of regulators. Using sulfur containing compounds as regulators, odorless and colorless dispersions which do not discolor are obtained if the dispersions after polymerization are treated with hydrogen peroxide. The dispersions are especially suitable as film forming component in dry bright emulsions for the care of floors.
