Flame retardant thermoplastic resin composition, shaped product, and stretched film

Abstract

Provided is a flame retardant thermoplastic resin composition having increased flame retardancy while also having improved moisture resistance. The flame retardant thermoplastic resin composition contains a thermoplastic resin and a bis(phosphine oxide) compound represented by the following formula (1). In formula (1), R1 is an optionally substituted alkylene group, an optionally substituted arylene group, or a divalent organic group represented by a formula: -Q1-Ar-Q2- (Ar is an optionally substituted arylene group and Q1 and Q2 are each, independently of each other, an optionally substituted alkylene group having a carbon number of not less than 1 and not more than 10), and R2 to R5 are each, independently of one another, an optionally substituted alkyl group, an optionally substituted aryl group, or an optionally substituted alkoxy group.

Dependencies are inferred from the claim text.
