摘要:
The present invention provides a phosphonate based compound represented by the following Chemical Formula 1 and a flameproof thermoplastic resin composition comprising (A) a thermoplastic resin and (B) a phosphonate based compound represented by the following Chemical Formula 1. The flameproof thermoplastic resin composition can exhibit good flame retardancy and impact strength. Further, the composition does not include a halogenated flame retardant and thus can provide environmental and safety benefits. wherein R1 and R2 are each independently C1-C4 alkylene and X is a cyano group.
