The invention provides compositions comprising at least one alkylphenol resin (constituent I) and, based on the alkylphenol resin, from 0.05 to 10% by weight of at least one salt of an aromatic base and of a sulfonic acid (constituent II).

Mineral oils with improved conductivity and cold flowability

The invention provides compositions comprising at least one alkylphenol-aldehyde resin (constituent I) and, based on the alkylphenol resin, from 0.005 to 10% by weight of at least one oil-soluble organic ammonium sulfonate (constituent II).

Alkoxylation catalyst

The new compounds consist essentially of ethylene oxide/propylene oxide block polymer units and oxyalkyleneated alkylphenol/aldehyde resin units, which are linked by methylene groups. They are prepared by reacting a block polymer of ethylene oxide and propylene oxide and an oxyalkyleneated alkylphenol/aldehyde resin with formaldehyde. The new compounds constitute especially advantageous breaking agents for petroleum.
