PURPOSE:To obtain the subject composition having improved flame-retardancy without deteriorating the characteristic properties of the base polymer by compounding a compound containing a halogen-substituted phenyl group, an antimony compound and a triazine compound. CONSTITUTION:100 pts.wt. of a polyester-type block copolymer having aromatic polyester segment and aliphatic polyester segment and/or polyactone segment is compounded with (A) 5-50 pts.wt. (preferably 8-30 pts.wt.) of a compound having halogen-substituted phenyl group, (B) 1-25 pts.wt. (preferably 3-15 pts.wt.) of an organic or inorganic antimony compound (preferably antimony trioxide) and (C) 0.5-10 pts.wt. (preferably 1-4 pts.wt.) of a triazine compound and/or its derivative (e.g., aminotriazines or oxytriazines). |
