<p>A method that includes: (a) heating a mixture that includes: (i) silicone, (ii) an organic polymer, and (iii) a depolymerization catalyst, wherein the heating is sufficient to depolymerize at least a portion of the silicone, to provide heated mixture comprising a cyclosiloxane and a residue. The method also optionally further includes (b) degassing the heated mixture to remove at least a portion of the cyclosiloxane, (c) forming an extrudate from the residue; and (d) heating the extrudate, sufficient to depolymerize at least a portion of remaining silicone located therein.</p> |
