Kinetic Analysis on the Stabilization Effects of Substituted POSS Powders Embedded in ?-Radiolyzed Polypropylene

The present paper proposes a reliable alternative for the increasing stability of polypropylene (PP) by modified polyhedral oligomeric silsesquioxanes (POSS). chemiluminescence measurements and FTIR records point complementarily out determinant influence substituents on progress oxidation during accelerated degradation caused ?-irradiation. main kinetic approach acting in radiation-induced aging recommends some studied structures POSS as appropriate compounds improving at low additive concentration. analysis results is based implication substituted POSS, whose contribution to limitation conditioned substituents. delay oxidative ?-irradiated consequence interaction between molecular PP fragments silanol moieties generated radiolysis, which are most vulnerable points structure.
