A composition is described in one aspect as comprising one or more propylene-&#x3b1;-olefin terpolymers; wherein the propylene-&#x3b1;-olefin terpolymer(s) possess a melting temperature (T) within the range of from less than 105&#xb0; C., and a heat of fusion (H) within the range of from less than 75 J/g; one or more polyolefin(s); and oil; wherein fillers are present, if at all, at a level that maintains a Haze value of 65% or less for the composition. The terpolymer in one embodiment is a polymer comprising at least 65 wt %, by weight of the terpolymer, of propylene-derived units, within the range of from 5 to 35 wt % of ethylene or other &#x3b1;-olefin and a diene such as ethylidiene norbornene, and in certain embodiments having a Mooney Viscosity (ML(1+4)@125&#xb0; C.) within the range of from 10 to 50 (ASTM D1646). The compositions can be cured to form transparent or translucent articles such as sheets that are also flexible.

Translucent propylene-based elastomeric compositions

Roofing composites and methods of producing the roofing composites are disclosed. The roofing composites are multi-layer structures in which two layers of the composite structures are bonded to each other by a thermoplastic elastomer composition. The layers are bonded to each other by heat fusing the elastomer composition in one embodiment. The composite structures have a variety of uses, including uses in construction materials such a roofing membranes, interior and exterior siding, and wall coverings.
