Abstract
The kinetics of diphenylcarbene (DPC) conversions in clusters with bir adicals (BR) formation has been studied in polycarbonate (PC) and poly methylmethacrylate (PMMA) at 77-125 K. The portion of carbene precurso r-diphenyldiazomethane (DDM) localized in micropores has been evaluate d from concentration dependences of BR yield. The correlation of kinet ic parameters of BR low temperature formation with molecular dynamic p roperties of spin probe has been observed in studied polymers. The str uctural modification of PC by aerosil filling effects on conversion ki netics of BR.
