Abstract
New compounds are disclosed for obtaining novel polymeric flameproofing agents. The former are diphenols of the general formula: ##STR1## where n=0 or 2. The latter are aromatic polyphenylphosphonates having recurring units of the general formula: ##STR2## in which n equals 0 or 2, and are obtained by reacting (I) with phenylphosphonyl chloride. The latter are especially useful for the flameproofing of polyester and finished or shaped articles based on polyester.
