<p>PURPOSE:To obtain the title composition improved in flame retardancy, mechanical properties, heat resistance, etc., while preventing the flame retardant from adhering to the mold or the molding by mixing a styrene resin with two specified halogenated aromatic diol ether derivatives and Sb2O3. CONSTITUTION:100 pts.wt. styrene resin (e.g. acrylonitrile/butadiene/styrene terpolymer) is mixed with 5-35 pts.wt. halogenated aromatic diol ether derivative of a weight-average molecular weight of 20000-100000, represented by formula I (wherein R1 and R2 are each H or a group of formula II or III; Y is Br; j is 0-5; X is Br or Cl; i is 1-4; and m is natural number), 5-35 pts.wt. another halogenated aromatic diol ether derivative of a weight-average molecular weight of 1000-9000, represented by formula I (the total of components B and C is 10-50 pts.wt.), 1-20 pts.wt. Sb2O3 of a mean particle diameter of 3mum or below, and optionally a flame-retarding aid, a filler, a lubricant, etc.</p> |
