Description of key information

According to REACH Annex VII, 9.3.1, column 2 the adsorption/desorption study does not need to be conducted as the substance and its relevant degradation products decompose rapidly. 

Key value for chemical safety assessment

Additional information

Under the test conditions required for covering this endpoint, the primary degradation product will react further. Therefore its adsorption / desorption cannot be measured. Quantifying the adsorption / desorption of the resulting polymer is technically not feasible because of its inhomogeneous composition, its low mobility inhibiting equilibration, and analytical limitations.
