Novel compounds comprising poly(polyhalonorbornenylalkyl)benzene as exemplified by 1,4-bis(1,3,4,5,6,7,7-heptachloro-5-norbornen2-ylmethyl)-benzene are prepared by reacting an aromatic hydrocarbon containing at least two alkyl substituents with 1,2dichloroethylene and thereafter reacting the resultant product with a polyhalo-substituted cycloalkadiene to form the desired compound. These compounds are useful for imparting flame retardant characteristics when admixed with a polymeric substance. |
