Abstract
The present invention relates to filled thermoplastic polyolefin compositions useful for use in sound-deadening articles for automotive applications comprising an olefin block copolymer, one or more linear ethylene polymer and/or substantially linear ethylene polymer, a propylene polymer, and a filler. Said compositions demonstrate a good balance of heat properties and stiffness such that it is particularly suitable for injection molding sound-deadening articles therefrom.
