A flame retardant resin composition including 100 parts by weight of component (A) or (B) and 0.01 to 30 parts by weight of red phosphorus (C) shows excellent flame retardancy even if the molding obtained from it is thin, and is excellent in mechanical properties, wet heat resistance and electric properties, being suitable for mechanical parts, electric and electronic parts, automobile parts, and housings and other parts of office automation apparatuses and household electric appliances. Component (A) may be a thermoplastic resin polyethylene terephthalate and ethylene terephthalate copolymers, and polyethylene terephthalate and/or ethylene terephthalate copolymer, and component (B) may be a thermoplastic resin selected from ##STR1## (O--R.sup.2 --O), (O--CH.sub.2 CH.sub.2 --O) and ##STR2## wherein R.sup.1, R.sup.2, and R.sup.3 are divalent aromatic residues.
A flame retardant resin composition, comprising 100 parts by weight of the following component (A) and 0.01 to 20 parts by weight of red phosphorus (C) covered with a thermosetting resin or 100 parts by weight of the following component (B) and 0.01 to 0.1 parts by weight of red phosphorus (C):
A flame retardant resin composition, comprising:
A flame retardant resin composition, comprising 100 parts by weight of a thermoplastic resin consisting of the following structural components (I), (II), (III) and (IV) and 0.01 to 0.1 parts by weight of red phosphorus (C)
A molding comprising a flame retardant resin composition consisting of 100 parts by weight of the following component (A) and 0.01 to 20 parts by weight of red phosphorus (C) covered with a thermosetting resin or 100 parts by weight of the following component (B) and 0.01 to 0.1 parts by weight of red phosphorus (C):
A process for producing a flame retardant resin composition, comprising the steps of melt-kneading part of the following component (A) or (B) and red phosphorus (C), to produce a composition high in red phosphorus content (1), and melt-kneading the remaining amount of the component (A) or (B) and the composition high in red phosphorus content (1) by a double-screw extruder:
A flame retardant agent for resins, comprising (a2) 100 parts by weight of polyethylene terephthalate and/or an ethylene terephthalate copolymer and (C) 0.01 to 250 parts by weight of red phosphorus.
A flame retardant resin composition, comprising
