Abstract
This invention relates to a butene-1 copolymer composition suitable as a wire coating material which is superior in flame retardance and even if it burns, no toxic gas is generated and superior in mechanical strengths, chacterized by comprising 20-55% by weight of a butene-1 copolymer containing 80-99 mol % of butene-1 unit and 1-20% of .alpha.-olefin unit having at least 5 carbon atoms and having an intrinsic viscosity [.eta.] of 1.0-7.0 dl/g measured in decalin at 135.degree. C. and a maximum melting point of 80.degree.-120.degree. C. measured by differential scanning calorimetric analysis and 80-45% by weight of an inorganic metal hydroxide and/or an inorganic metal hydrate which have an average particle size of 0.05-6 m.
