The invention provides a composition comprising the following: A) an ethylene/&#x3b1;-olefin/diene interpolymer; B) an ethylene/&#x3b1;-olefin copolymer with a Mooney Viscosity [ML(1+4) at 125&#xb0; C.] greater than 40; and C) a peroxide; and wherein the &#x3b1;-olefin of the ethylene/&#x3b1;-olefin copolymer of component B comprises at least four carbon atoms; and wherein component A is present in an amount from 50 to 95 weight percent, based on the sum weight of components A and B.

Polymer compositions with improved retention of properties under mechanical and thermal stresses

A thermoplastic vulcanizate composition comprising from 5 wt % to 95 wt %, based on the total weight of the thermoplastic vulcanizate composition, of a first component comprising a first propylene-based polymer selected from the group consisting of (i) propylene/&#x3b1;-olefin copolymers comprising from 1 to 20 wt % &#x3b1;-olefin and characterized by a g' ratio of less than 1, measured at interpolymer number average molecular weight (Mn), an MFR (2.16 kg @ 230&#xb0; C.) greater than or equal to 0.01, a density greater than or equal to 0.850 g/cc, and a molecular weight distribution, Mw/Mn, less than or equal to 3.5, and (ii) combinations thereof; and from 5 wt % to 95 wt %, based on the total weight of the thermoplastic vulcanizate composition, of a second component selected from the group consisting of curable or vulcanizable rubbers, having a density from 0.85 to 0.88 g/cc, Ifrom 0.001 to 5 g/10 min, and a Mooney viscosity from 5 to 400, and combinations thereof; wherein at least one of the rubbers is vulcanizable; wherein the thermoplastic vulcanizate composition has a tensile strength at break of greater than or equal to 8 MPa and tear strength at 23&#xb0; C. of at least 190 lb-f/in. is provided. Methods of making the composition and articles made from the composition are also provided.

Thermoplastic vulcanizate composition, method of producing the same, and articles made therefrom

The invention provides a composition comprising a first composition, which first composition comprises the following:

Polymer compositions, methods of making the same, and articles prepared from the same

This invention relates to bituminous compositions comprising an interpolymer and a bituminous material and methods of making and using same. The interpolymer may comprise ethylene, at least one alpha-olefin, and, optionally, at least one diene and the interpolymer is derived from polymer particles having a surface coating comprising a partitioning agent. Methods of making and using the bituminous compositions are also described.

Bituminous compositions and methods of making and using same

A thermoplastic elastomer consisting essentially of a copolymer comprising a mixture of ethylene; one or more alpha-olefins having 3 to 12 carbon atoms; and, optionally, a diene, said copolymer being in an uncrosslinked state and having a crystallinity in the range of about 2 to about 40 percent by weight based on the weight of the copolymer wherein about 15 to about 85 percent by weight of the crystallinity melts at a temperature above 80.degree. C.; about 15 to about 85 percent by weight of the crystallinity melts at a temperature below 80.degree. C.; and the crystalline melting temperatures differ by at least about 30.degree. C.
