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. n CONSTITUTION: 100pts.wt. of a vulcanized rubber such as a tire or a hose, are treated at 0W100°C, with addition of 1W30pts.wt. of a diacyl peroxide of decomposition temperature ≤90°C, such as lauroyl peroxide or benzoyl peroxide, and a solvent which swells the vulcanized rubber, such as CCl 4 or Chlorobenzene, and/or 50W2,000 parts, by volume, of a radical-polymerizable monomer such as (meth) acrylic acid or styrene. n USE: An adhesive, a processing oil, a waterproof sheet, a sealing material, etc. n COPYRIGHT: (C)1981,JPO&Japio |
