ABSTRACT:
The char-forming characteristics of aromatic polymers containing one or more combustion resistant components are improved by incorporating therein a polybenzyl, a polyallyl, or an allyl/benzyl moiety. As an example, a styrene polymer comprising a halogenated comonomer such as bromostyrene is rendered char-forming by the presence of copolymerized vinylbenzyl chloride in the styrene polymer. Such polymeric compositions are useful in the manufacture of shaped articles such as housings for electrical appliances.
