FLAME RETARDANT, AND FLAME-RETARDANT RESIN COMPOSITION CONTAINING SAME

摘要

A flame retardant containing as a main component an organic phosphorus compound represented by general formula (I): (in the formula, R is a hydrogen atom or a C1-4 alkyl group or monochloroalkyl group, Y is a C3-6 alkylene group or a group represented by -CH2CH2(OCH2CH2)zOCH2CH2- (z is an integer of 0-3), n is an integer of 0-10), wherein the flame retardant has a contained amount of a compound represented by general formula (II): (in the formula, R, Y, and n are defined the same as in general formula (I)) of 4 area% or less when the flame retardant is measured by gel permeation chromatography (GPC); and a flame-retardant resin composition containing this flame retardant and a resin.
