  • Resol-type para-octylphenol-formaldehyde co-condensation resin and method for producing the same
    Patent number: 9518141
    Abstract: A resol-type para-octylphenol-formaldehyde co-condensation resin and a method for producing the same are provided, the resol-type para-octylphenol-formaldehyde co-condensation resin having a content of a para-octylphenol monomer of 1 wt. % or less, having a total content of an aliphatic hydrocarbon, a halogenated aliphatic hydrocarbon, an aromatic hydrocarbon, a halogenated aromatic hydrocarbon, and an alcohol having 1 to 8 carbon atoms of 1 wt. % or less, the aliphatic hydrocarbon, the halogenated aliphatic hydrocarbon, the aromatic hydrocarbon, the halogenated aromatic hydrocarbon, and the alcohol having a boiling point of 60° C. or more, having a softening point of 70 to 105° C., and having an acid value of 20 to 28 KOHmg/g. The resol-type para-octylphenol-formaldehyde co-condensation resin can be used as a resin cross-linking agent for a rubber.
