PURPOSE:The titled composition having high heat stability and blooming resistance, containing polyolefin, an organic halogenous flame-retardant, an aliphatic carboxylic acid having a melting point <= a specific value and a metallic sat of an aliphatic carboxylic acid. CONSTITUTION:(A) 100pts.wt. polyolefin, preferably polypropylene, is blended with (B) 0.5-30pts.wt., preferably 1-20pts.wt. organic halgenous flame-retardant, preferably an etherified tetrabrominated bisphenol A shown by the formula I (R1 and R2 are 2-10C alkyl bonding two or more Br), a brominated alkyl isocyanurate shown by the formula II (R5, R6, and R7 are as shown for R1 and R2), chlorinated paraffin, etc., (C) 0.01-5pts.wt., preferably 0.03-3pts.wt. fatty acid having <=60 deg.C melting point, preferably caproic acid, caprylic acid, etc., (preferably several fatty acids are used), and (D) 0.01-5pts.wt., preferably 0.3-3pts.wt. metallic salt of aliphatic carboxylic acid, preferably stearate and preferably antimony trioxide. |
