<p>PURPOSE:To regenerate waste fluororubber using an easily controllable safe process, easily, by dissolving an amine in a medium for swelling a fluororubber, and immersing crushed waste fluororubber in the medium. CONSTITUTION:Regenerated fluororubber is produced by immersing crushed waste fluororubber in a fluororubber-swelling medium (preferably alcohol or ketone) containing a 3-20C alkylmonoamine as a solute. The amount of the amine is 0.05-0.5mol per 1 liter of the medium, and 0.05-0.2mol per 1kg of the waste rubber.</p> |
