Abstract
A fire-retardant and radiation resistant molded resin product is prepared by blending a resin with a halogenated acenaphthylene compound of the formula: ##STR1## wherein X is chlorine or bromine and R is alkyl, alkoxy or alkylester of 1 to 4 carbon atoms such that when m is 0, n is an integer of 2 to 8; when m is an integer of 1 to 4, n is an integer of 2 to 7 and n+m is .ltoreq.8 and when m is more than 2, R may be the same or different; and, after molding said blend, generating free radicals within said blend.
