Notes:
We have screened various multifunctional Friedel-Crafts alkylation and acylation reagents for their charring ability in impact polystyrene. Only benzyl chloride reagents with Sb2O3-halogen catalysts promoted crosslinking; the result is increased char yields and decreased fuel production and thereby improved fire resistance. Selected systems were evaluated for ignition, extinction, flamespread, and smoke generation; chars were fully characterized.
