摘要

The purpose of the present invention is to provide a flame retardant which has excellent heat resistance and which, when added to synthetic resins, in particular, polyester-based resins, is capable of greatly improving the flame retardancy of the synthetic resins. The flame retardant comprises a compound represented by general formula (1). In general formula (1), R1 and R3 each independently represent a monovalent aromatic group optionally having one or more substituents; X1 and X2 each independently represent a direct bond, a C1-8 alkylene group, an oxygen atom, a nitrogen atom, or a sulfur atom, any adjoining carbon atoms of the C1-8 alkylene group optionally having an oxygen, nitrogen, or sulfur atom interposed therebetween; R2 represents -CH2CH2- or -CH2CH2CH2-; and n is a number of 1-10,000.
