PROBLEM TO BE SOLVED: To provide a p-tert-octylphenol-sulfur chloride co-condensed resin useful as a resin-crosslinking agent having characteristics of improving viscoelastic characteristics compared to the case using sulfur without damaging breaking characteristics when added to a rubber.SOLUTION: There is provided a p-tert-octylphenol-sulfur chloride co-condensed resin obtained by reacting 1.2-1.8 mol of sulfur monochloride with 1 mol of p-tert-octylphenol, having 25-34 wt.% of a sulfur content in the resin, and usable as a resin curing agent. |
