Abstract
PURPOSE: To prepare the title flame-retardant of good compatibilily with resins even in the absence of dispersants, and capable of affording molded products free from any degradation of physical properties, by mixing a specific halogen compound, an inorganic flame-retarding substance, and an inorganic matter.
CONSTITUTION: A solvent such as methylene chloride is added to a bromine compound as represented by the formula, namely, tetrabromobisphenol A (or its derivative), brominated phenylalkyl ether, brminated phenylmethacrylic ester, or perchloropentacyclodecane compound. The amount of the solvent to be added is preferably 15W20 wt.% based on the bromine compound. If required, another halogen compound such as chlorinated polyethylenl, etc. is then added so that the bromine compound accounts for ≥20 wt.%. This is fallowed by addition of an inorganic flame-retarding substance such as antimony trioxide, preferably in such an amount as to be double to ten times that of the bromine compound, and then an inorganic matter such as talc, etc. is incorporated. The resulting mixture is made into pellets by an extrusion pelletizer, which are then dried to obtain the objective flame- vretardant composition.
