Abstract
Abstract A composition for backing a carpet, which contains (a) 5 to 65% by weight of an olefin-polar monomer copolymer having a polar monomer content of 5 to 40% by weight, (b) 1 to 50% by weight of a synthetic oil comprising one or more non-condensed tricyclic aromatic hydrocarbon compounds having a boiling point of 250 DEG C. or higher and a molecular weight of 258 to 482, and being liquid at room temperature, (c) 30 to 90% by weight of an inorganic filler, and, if necessary, up to 50% by weight of a solid low-molecular compound component. The composition is particularly useful for automobile carpets and carpet tiles. The composition provides flexibility during blending, a high flexibility, and, in particular, a superior performance at low temperatures.
