The fillers generate stronger elastomers and are of great influence on the thermal stability and flammability composites. Organic and inorganic fillers, such as carbon black or silica, are often added to the elastomers. Usually

,4-DNPHs are made by column and thin-layer chromatography. Some 2,4-DNPH derivatives are analyzed by direct Gas–Liquid Chromatography (GLC). An important aspect with regards to the GLC separation of the 2,4-DNPH derivatives lies in their thermal stabilities

Thermal transitions of elastomers are classified and problems concerning their stability are discussed. It is concluded that in the case of general-purpose elastomers no simple correlation exists between the energy of the bonds in the skeleton of a chain and their thermal stability. This also holds for the parameters of the physical structure of the chains. A high tendency to cross-linking, a high concentration of cross-links and their chemical structure give rise to a more perceptible effect.

Cefuroxime axetil is a second-generation cephalosporin used to treat or to prevent infections proven (or strongly suspected to be caused by) bacteria. It has a carbamoyl group which gives a sizable metabolic stability, a
