The present disclosure provides a composition. In an embodiment, the composition includes a non-irradiated ethylene/propylene/non-conjugated polyene terpolymer (nr-terpolymer) and a branched ethylene/propylene/non-conjugated polyene terpolymer (b-terpolymer). The b-terpolymer has: (A) a Mooney viscosity (ML 1+4 @ 125° C.) from 35 MU to 120 MU; (B) a rheology ratio from 55 to 110; and (C) a phase angle δ from 20° to 39°.

Process to form a tile using low temperature heat lamination

Fibers that exhibit good elasticity or extensibility and tenacity, and low modulus are prepared from propylene-based copolymers. The propylene-based copolymers comprise at least about 50 weight percent (wt %) of units derived from propylene and at least about 8 wt % of units derived from one or more comonomers other than propylene, e.g., ethylene. Particularly preferred propylene copolymers are characterized as havingC NMR peaks corresponding to a regio-error at about 14.6 and about 15.7 ppm, the peaks of about equal intensity. In one aspect of the invention, fibers are subjected to stress-induced crystallization by subjecting the fiber to tensile elongation during draw.
