摘要: A bitumen composition suitable for a carpet tile backing is provided having from 12 to 35 wt. % bitumen, 50 85 of an inorganic filler such as calcium carbonate and 0.5 20 acid functionalized polyolefin selected acrylic acid, maleic anhydride grafted isotactic polypropylene. The cold flow characteristics the can be improved by incorporating 1 10 atactic
