Abstract

A flame retardant moldable thermoplastic resin composition consisting of a thermoplastic resin and a flame retardant consisting of a combination of a low molecular weight phosphate having a molecular weight of about 500 to about 2000 and a high molecular weight phosphate having a molecular weight of about 2300 to about 11,000 and to articles molded therewith. The composition has a high heat deflection temperature, good impact resistance, excellent flame retardancy and good flow for easier processing.
