Abstract

Abstract A fire-retardant 1-butene resin composition composed of (A) 100 parts by weight of a 1-butene polymer or copolymer containing 0 to 20 mole % of an olefin with 2 to 20 carbon atoms other than 1-butene as a comonomer, (B) 110 to 1,000 parts by weight of an inorganic hydroxide selected from the group consisting of magnesium hydroxide and aluminum hydroxide, and (C) 10 to 150 parts by weight of a graft-modified olefin resin resulting from grafting of an unsaturated carboxylic acid or its functional derivative to a polymer or a copolymer of an olefin having 3 to 8 carbon atoms or a copolymer of said olefin with up to 30 mole % of ethylene.
