Abstract
PURPOSE: To prepare the title composition having improved flame-retardancy, free from toxicity and corrosiveness, and useful for the production of a thin-walled molded article, by compounding a composite flame-retardant composition composed of a polyolefin and magnesium hydroxide, with polyvinyl alcohol, et.
CONSTITUTION: (A) An olefin polymer, (B) Mg(OH)2 pref. having a specific surface area of ≤ 45 m2/g and (C) polyvinyl alcohol having an average degree of polymerization of ≤ 10,000 and/or an ethylene/vinyl alcohol copolymer containing ≥ 0.1%, pref. 30-80% of vinyl alcohol, are mixed together by a conventional kneader at a temperature below the heat decomposition temperature of Mg(OH)2. The amount of (A)+(C) is 70-20 wt%, and that of (B) is 30-80 wt.%. The weight ratio of (C)/(A)+(C) is 0.01-0.96, pref. 0.02-0.5.
EFFECT: The amount of Mg(OH)2 necessary to attain a required flame retardancy can be reduced, which results in a molded product having improved impact resistance.
