| titleOfInvention | Flame-resistant polycarbonate containing units from halogenated pyrimidine compounds in the polymer chain |
| abstract | Flame-resistant thermoplastic branched polycarbonates of high molecular weight are prepared from: n (1) a carbonate precursor; n (2) at least one dihydroxyaromatic compound of formula: ##STR1## where: R is a single bond, or a substituted or non-substituted linear or branched C 1 -C 5 alkylene radical, or a group chosen from O, S, SO 2 and CO; n X and Y, which may be the same or different, are H or CH 3 ; n m and n, which may be the same or different, are whole numbers from 1 to 4; n (3) at last one halogenated pyrimidine compound of formula: ##STR2## where: R 2 , R 3 , R 4 , which may be the same or different, are chlorine or bromine or hydrogen, on condition that at least one is chlorine or bromine; n R 1 is chlorine or bromine, or a radical of formula: ##STR3## where Z is NH or S or O; (4) at least one polyfunctional organic compound as branching agent, characterized by possessing at least three equal or different groups chosen from the groups OH, COOH, COCl and SO 2 Cl. |
