Popis:	The kinetics of diphenylcarbene (DPC) conversions in clusters with biradicals (BR) formation has been studied in polycarbonate (PC) and polymethylmethacrylate (PMMA) at 77–125 K. The portion of carbene precursor-diphenyldiazomethane (DDM) iocalized in micropores has been evaluated from concentration dependences of BR yield. The correlation of kinetic parameters of BR low temperature formation with molecular dynamic properties of spin probe has been observed in studied polymers. The structural modification of PC by aerosil filling effects on conversion kinetics of BR.
