<p>The present invention provides a flame retardant that can be used as a polymer, or a novel material that can be used as a raw material for a flame retardant. In particular, the present invention provides a compound represented by formula (A). In the formula, Ra and Rb are each independently a substituent such as hydrogen, an aryl group, a substituted aryl group, or an alkyl group, or Ra and Rb together form an additional cyclic skeleton; R1 and R2 are each independently the same or different radical polymerizable groups; and R3, R4, and R5 are each independently a substituent such as a hydrogen atom, a halogen atom, an alkyl group, or a substituted alkyl group.</p> |
