摘要：
The molecular mobility of interfacial layers in some polymers filled with silica (Silochrome) was studied using a spin label adsorbed on the surface of the filler particles. It is noted that stable nitroxyl radicals adsorbed on the polymer surface or grafted to the surface can be used. It is established that the differences in molecular mobility between the polymer layers located near the polymer surface and far from the surface sharply decrease with increasing glass transition temperature.
