Abstract

Three hosphorus containing polyhedral oligomeric silsesquioxanes (POSS) with perfect T₈ caged structures were synthesized successfully by the addition reaction between octa vinyl POSS and diphenylphosphine (DPP), diphenylpsphine oxide (DPOP),or 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO). The impacts of DPP-POSS, DPOP-POSS, and DOPO-POSS on the pyrolysis and fire behavior of an epoxy resin (DGEBA/DDS) were investigated under temperature programmed heating (TGA-FTIR), forced flaming conditions (cone calorimeter) and small flame conditions (LOI and UL-94). The flame retardancy performance and flame retardancy mechanisms of DPP-POSS, DPOP-POSS, and DOPO-POSS were assessed and discussed through the condensed phase analysis and gaseous phase analysis.
