Abstract
PURPOSE: Titled composition which can form sheets having excellent impact resistance and being resistant to hazing, prepared by blending a propylene-ethylene block copolymer with a high-density polyethylene.
CONSTITUTION: The composition for polyolefin type sheets is prepared by blending 65W95wt% of (a) an ethylene-propylene block copolymer, ethylene content 3W 25wt%, heat-absorption peak ranges (values when measured on a differential calorimeter) 118W130°C and 158W166°C, isotactic index at least 90wt%, with 5W35wt% of (b) a high-density polyethylene, density ≥0.942g/cm3. Also, to the resulting composition there may be added 3W150wt% of a low-density polyethylene and/or an ethylene-propylene rubber.
