ESR INVESTIGATIONS ON THE THERMAL-DEGRADATION OF POLYEPICHLOROHYDRIN

Electron spin resonance investigations on the thermal degradation in a ir of stabilized and crude polyepichlorohydrins are reported. The temp erature dependence of resonance line parameters, in the temperature ra nge 250-500 degrees C, has been investigated. The activation energy ha s been estimated for the total free-radical generation processes. lit situ experiments on crude and stabilized polyepichlorohydrins are repo rted. For the sample stabilized with amines the appearance of nitroxid e-like free radicals has been noticed. (C) 1997 Elsevier Science Limit ed.
