PROBLEM TO BE SOLVED: To provide an olefin polymer compsn. which gives out little smoke during extrusion into fibers or films. SOLUTION: This compsn. comprises an olefin polymer (i) contg. an acid- neutralizing agent other than a satd. or unsatd. fatty acid metal salt and a stabilizer system (ii) dispersed therein. The stabilizer system contains a phosphite (A) comprising either 2,2',2"-nitro[triethyl-tris(3,3',5,5'-tetra-tert-butyl-1,1- biphenyl-2,2'-diyl)phosphite] or tris(2,4-di-tert-butylphenyl)phosphite and N,N- dialkylhydroxylamine, banzofuranone, or their mixture (B). The neutralizing agent is pref. selected from among calcium lactate, calcium hydroxide, calcium oxide, and their mixtures. |
