Abstract:
PURPOSE: A novel phosphorus compound and a flame retardant thermoplastic resin composition containing the same are provided to enhance anti-hydrolysis property and thermal resistance. CONSTITUTION: A phosphorus compound is denoted by chemical formula 1. A method for preparing the phosphorus compound of chemical formula 1 comprises: a step of reacting phosphorus oxychloride and a compound of chemical formula 2; and a step of reacting a reactant with hydroquinone. A flame retardant thermoplastic resin composition contains 0.1-50 weight parts of the phosphorus compound and 100 weight part of thermoplastic resin. The thermoplastic resin is polycarbonate resin.
Abstract:
PURPOSE: A thermoplastic resin composition, a plastic molded article produced therefrom, and a method for preparing a polymerizable phosphorus-based compound are provided to ensure excellent flame retardancy, impact resistance, heat resistance, and fluidity. CONSTITUTION: A thermoplastic resin composition comprises: 100 wt % of a base resin including 30 to 100 wt % of a polycarbonate-based resin; and 0.1 to 40 wt % of a polymerizable phosphorus-based compound represented by chemical formula 1. In chemical formula 1, A is a single bond, C1-C5 alkylene, C1-C5 alkylidene, C5-C6 cycloalkylidene, -S- or -SO2-; R is C1-C20 aryl; and n is an integer of 4 - 500. The base resin comprises 30~100 weight% of a polycarbonate resin and 0~70 weight% of a rubber-modified aromatic vinyl polymer.
