PURPOSE:To obtain the title odorless composition excellent in permanent antistatic property, mechanical properties and hue, by mixing a thermoplastic polyether-ester with a specified polyether-ester-amide. CONSTITUTION:10-70wt% poly(alkylene oxide) glycol (a) of an MW of 500-3,000 is condensed with a 2-6C aliphatic diol (b) and a dicarboxylic acid (c) to obtain a thermoplastic polyether-ester (A). Separately, a 6C or higher lactam, and aminocarboxylic acid or a salt (d) of a 6C or higher diamine with a dicarboxylic acid is reacted with poly(ethylene oxide) glycol (e) of a number- average MW of 200-10,000 and a 4-20C dicarboxylic acid (f) to obtain a polyether-ester-amide (B) which is a block copolymer comprising polyamide block units and 10-90% polyether-ester units. 99.9-50% component A is mixed with 0.1-50% component B and, optionally, an antioxidant, a filler, a colorant, a plasticizer, etc. (C) and the mixture is melt-kneaded at 150-400 deg.C. |
