Abstract
Filled thermoplastic compositions useful e.g., as sound-deadening sheeting for automotive carpet are obtained by blending at least one ethylene/α-olefin interpolymer; about 40-95 percent by weight of filler; and optionally elastomeric polymers.
Claims20
A composition comprising:
- (a) at least one interpolymer of ethylene with at least one α-olefin comonomer, the interpolymer having a molecular weight distribution, Mw/Mn, of less than about 3.5 and a composition distribution, as measured by composition distribution breadth index (CDBI) of greater than about 50 percent;
- and
- (b) from about 85 to about 95 percent of at least one filler based on the total weight of the composition,
- wherein the composition is thermoplastic in nature.

A composition comprising:
- (a) at least one interpolymer of ethylene with at least one α-olefin comonomer, the interpolymer having a molecular weight distribution, Mw/Mn, of less than about 3.5 and a composition distribution, as measured by composition distribution breadth index (CDBI) of greater than about 50 percent;
- and
- (b) from about 40 to about 95 percent of at least one filler based on the total weight of the composition;
- wherein the composition is thermoplastic in nature, and absent a plasticizer.
