| description | The invention relates to a method according to claim 1 for the commercial implementation of a pyrolysis, and to pyrolysis devices for the pyrolysis of pyrolysis stock used in this method. The pyrolysis stock contains a polymeric compound having at least one structural polyurethane unit of the formula (I), wherein Q is a hydrocarbon group with 2 to 8 carbon atoms, preferably 3 to 8 carbon atoms, and n represents a number from 2 to 4, most preferably 2, and -* represents a covalent bond to the polymer backbone. The method and the pyrolysis device according to the invention allow, even with higher compounds of pyrolysis stock an amount of pyrolysis product to be obtained that contains cleavage products which can be reused for the synthesis of polyurethane-containing material. |
