| titleOfInvention |
Preparation of bromine-containing polymers useful as flame retardants |
| abstract |
The present invention relates to a Friedel-Crafts alkalization reaction of tetrabromoxylylene dihalide or of tetrabromoxylylene dihalide with pentabromobenzyl halide with a reactant having one or more 6-membered aromatic rings, and bromine from the reaction mixture. A process for preparing a bromine-containing polymer, comprising the step of separating the containing polymer, wherein the reaction proceeds in a solvent in the presence of a Friedel-Crafts catalyst. The polymer so formed and its use as a flame retardant is another aspect of the present invention. [Selection figure] None |
