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

摘要

PURPOSE: A novel phosphonate compounds and flame retardant thermoplastic resin composition containing the same are provided to ensure stability and strength and to prevent environmental pollution. CONSTITUTION: A phosphonate compound is denoted by chemical formula 1. In chemical formula 1, R1 is alkyl group of C1-C4, phenyl group, or cyano group; and R2 and R3 are independently hydrogen and alkyl of C1-C4. A flame retardant thermoplastic resin composition contains 100 weight parts of thermoplastic resin and 0.5-30 weight parts of phosphonate compounds of chemical formula 1. The composition further contains 1-20 weight parts of phosphate flame retardant compound.
