摘要：Polyhalophthalimidoalkyl-functional carbonates may be employed as fireretardant 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, and2-(hydroxyalkylcarbamyl)-polyhalobenzoic acids are useful as intermediates in thepreparation of the carbonates.
