NOVEL DIPHENOXYPHOSPHORYL FLAME RETARDANT, METHOD FOR PREPARING THEREOF, AND FLAMEPROOF THERMOPLASTIC RESIN COMPOSITION CONTAINING THE SAME

摘要

PURPOSE: A diphenoxyphosphoryl flame retardant is provided to obtain excellent flame retardant property, to be environment-friendly used without using a halogen retardant when a resin is processed or combusted, and to enable a user to easily handle the diphenoxyphosphoryl flame retardant due to solid phase. CONSTITUTION: A diphenoxyphosphoryl flame retardant is marked as a chemical formula 1. In the chemical formula 1, R1 and R2 are hydrogen or an alkyl group with C1-C6 and n is integer of 0-5. A method for manufacturing the diphenoxyphosphoryl flame retardant includes a step of reacting a compound of a chemical formula 2 with a diketone compound of a chemical formula 3. In the chemical formula 2, R1 and R2 are hydrogen or the alkyl group with C1-C6.
