For example, after polymer 2a was pyrolyzed in air at 900 °C, similarly to the combustion analysis, a small amount of carbon was detected in the remaining ash by EDX analysis, in addition to large amounts of silicon and oxygen. Such phenomena are often observed for the other organometallic polymers [12]
