ABSTRACT:
Polyhalophthalimidoalkyl-functional carbonates may be employed as fire retardant additives to polymers. Examples of such carbonates are 2-(tetrabromophthalimido)ethyl 2,4,6-tribromophenyl carbonate, 2-(tetrabromophthalimido)ethyl pentabromophenyl carbonate and bis[2-(tetrabromophthalimido)ethyl] carbonate.
Polyhalophthalimidoalkyl haloformates, N-(hydroxyalkyl)-polyhalophthalimides, and 2-(hydroxyalkylcarbamyl)-polyhalobenzoic acids are useful as intermediates in the preparation of the carbonates.
