  The part for the TG-DSC analysis must be rewritten again, since there are several misunderstandings.
  In the case of simultaneous measurement of DSC and TG, two different effects can be observed from the DSC signal, in the degradation area of the studied sample. The first one is the decomposition of the sample which is always an exothermic event for a DSC measurement and the second one is the mass loss due to the decomposition which is an endothermic effect. The DSC signal in this case will present a plateau or an endothermic/exothermic peak since the final signal is the sum of the exothermic phenomenon due to the decomposition, and the endothermic one due to the mass loss of the sample. The shape depends on the enthalpy of the two events.
  In addition, two steps of mass loss have been recorded for the samples under study. The first one can be found in the area of 30 - 200 C, with one step of mass loss for the samples RSF and ALK-SF and two overlapped mass loss steps for the other samples. The author must discuss this difference while taking into account that no direct information can be obtained about the part of the sample that decomposes, from the TG measurements.
  The samples must be studied with TG-MS or other techniques in order to be sure about the decomposition scheme. The second area of mass loss is among 200 ¨C 400 C, during which two overlapped decomposition steps are obvious. This is more obvious from the DTG figure. For this area also other techniques must be used for the determination of the decomposition scheme. Using the above comments the possibility of the silane grafting must be discussed.
