<p>PURPOSE:To efficiently decompose a vulcanized rubber at a low temperature and to obtain a liquid or semisolid rubber decomposition product, by treating the vulcanized rubber with a solution composed of a diacyl peroxide, and of a solvent for the vulcanized rubber and/or a radical-polymerizable monomer. CONSTITUTION:100pts.wt. of a vulcanized rubber such as a tire or a hose, are treated at 0-100 deg.C, with addition of 1-30pts.wt. of a diacyl peroxide of decomposition temperature <=90 deg.C, such as lauroyl peroxide or benzoyl peroxide, and a solvent which swells the vulcanized rubber, such as CCl4 or Chlorobenzene, and/or 50-2,000 parts, by volume, of a radical-polymerizable monomer such as (meth) acrylic acid or styrene. USE:An adhesive, a processing oil, a waterproof sheet, a sealing material, etc.</p> |
