Abstract

PURPOSE:To provide a compounding ingredient for rubber capable of remarkably improving the tackiness, tensile strength and elongation of a rubber composition, by reacting the distillation residue obtained by the purification of p-tert- butylphenol, etc., with an aldehyde. CONSTITUTION:Isobutylene oligomer is made to react with phenol in the presence of a catalyst, and the obtained p-tert-butylphenol or p-tert-octylphenol is purified. 100pts.wt. of the obtained distillation residue is added with preferably 20-50pts.wt. of an aldehyde (e.g. paraformaldehyde) and preferably 0.1- 0.5pts.wt. of a basic catalyst such as calcium hydroxide or an acidic catalyst such as hydrochloric acid, and made to react with each other by heating at 80-200 deg.C to obtain the objective compounding ingredient for rubber. USE:Rubber composition for tire.
