Abstract

PURPOSE: To prepare the title composition having excellent sound insulating and absorbing characteristics, and processability, by melting and mixing a polyolefin with specific amounts of a specific thermoplastic rubber and an inorganic filler.
CONSTITUTION: A composition obtained by the melt-mixing of (A) a polyolefin, (B) a thermoplastic rubber incompatible with the polyolefin (e.g. styrene-butadiene rubber), and (C) an inorganic filler such as barium sulfate, zinc oxide, etc. The amount of the (B) component is more than 10vol% of the whole composition and less than the (A) component, and that of the (C) component is 20W50vol%. Combined use of the polyolefin with minor amount of other resin such as polystyrene improves the paintability without lowering the sound insulating and absorbing characteristics and processability of the original composition.
