摘要 |
<p>PCT No. PCT/EP96/02488 Sec. 371 Date Dec. 12, 1997 Sec. 102(e) Date Dec. 12, 1997 PCT Filed Jun. 7, 1996 PCT Pub. No. WO97/00283 PCT Pub. Date Jan. 3, 1997The invention relates to a process for recycling cured or partly cured polysulfide and/or polymercaptan compositions. Recycling is carried out in a non-volatile liquid with addition of a depolymerizing agent, preferably a sulfur-containing vulcanization accelerator known from rubber technology. The depolymerisate may be added to the curing component of two-component polysulfide and/or polymercaptan adhesives/sealants or coating materials in large quantities without any significant effect on its stability in storage or curing characteristics.</p> |
