NOVEL PHOSPHOANATE BASED COMPOUND AND FLAME RETARDANT THERMOPLASTIC RESIN COMPOSITION INCLUDING THE SAME

摘要

PURPOSE: An environment-friendly flame-retardant thermoplastic resin composition is provided to ensure excellent stability to fires, flame retardancy and strength without a halogen-based retardant causing environmental contamination. CONSTITUTION: A phosphonate-based compound is represented by chemical formula 1. In chemical formula 1, R1 and R2 are independently C1-C4 alkylene and X is a cyano group. A flame retardant thermoplastic resin composition comprises a thermoplastic resin and a phosphonate-based compound represented by chemical formula 1. The flame retardant thermoplastic resin composition 100 parts by weight of the thermoplastic thermoplastic resin and 0.5~30 parts by weight of the phosphonate-based compound.
