摘要

PROBLEM TO BE SOLVED: To provide a sterically hindered phenyl-containing phosphonate compound, a method for producing the same, and a flame-retardant polycarbonate resin composition containing the same.;SOLUTION: Provided are a sterically hindered phenyl-containing phosphonate compound represented by chemical formula (1), a method for producing the same, and a flame-retardant polycarbonate resin composition containing the same. In chemical formula (1), R₁ is a 1-6C straight or branched alkyl group or a 6-14C aryl group; R₂ is a 1-6C linear alkyl group or a 3-6C branched alkyl group; and ns, which are independent of each other, are integers of 1-3.;COPYRIGHT: (C)2009,JPO&INPIT
