PURPOSE:To provide the titled compsn. having excellent mechanical properties, dielectric properties, flame retardance and resistance to chemicals and water, consisting of a 3-methylbutene-1 polymer, a specified org. flame retarder, an inorg. flame retarder and a polymer. CONSTITUTION:100pts.wt. 3-methylbutene-1 polymer (A) having a density of 0.88-0.90g/cm<3> (23 deg.C) and an MI of 0.1-50g/10min is blended with 5-200pts.wt. org. flame retarder (B) of formula I (wherein R is a 1-20C hydrocarbon group which may have O' in its skeleton and substituted by halogen), 5-200pts.wt. inorg. flame retarder (C) (e.g., Sb2O3) and 1-40pts.wt. polymer (D) of formula II (wherein X is O, S, Se; R1-R4 are each H, halogen, a 1-20C hydrocarbon group which may have O or halogen; n is 20 or above). |
