PURPOSE:To obtain the titled composition outstanding in drawing processability, suitable for smokeproof nets, wall covering materials, etc., by incorporating specified amount of a hydrocarbon polymer in a resin composition comprising polyolefin resin and inorganic flame-retardant. CONSTITUTION:The objective composition can be obtained by incorporating (A) 100pts.wt. of a composition comprising A1: 90-20(pref. 80-30)wt.% of a polyolefin resin (e.g., polypropylene with a melt flow rate 0.3-10g/10min) and A2: 10-80(pref. 20-70)wt.% of an inorganic flame-retardant (e.g., sodium antimonate) with (B) 1-20(pref. 3-10)pts.wt. of a hydrocarbon polymer having at least one hydroxyl group at the terminal with the main chain either saturated or partially saturated. |
