摘要 |
A composition that can be used as foam composition is disclosed, which comprises or is produced from an ethylene acrylate dipolymer, an acid copolymer, and optionally a soft ethylene polymer. The ethylene acrylate dipolymer comprises repeat units derived from ethylene and at least one alkylacrylate. The acid copolymer comprises repeat units derived from ethylene and acrylic acid, methacrylic acid, or combinations thereof. The soft ethylene polymer comprises ethylene and an α-olefin, vinyl acetate, or combinations thereof. |

1. An article comprising, or produced from, an ethylene acrylate dipolymer, an acid copolymer, and optionally a copolymer of ethylene and an α-olefin wherein
the article is a footwear foam having a density lower than 2 g/cc, a foam hardness of about 25 to about 55 Asker C; a split tear strength of at least 2.5 kg/cm; and a compression strength of at least 28 pounds/in2; the ethylene acrylate dipolymer is derived from ethylene and a comonomer selected from the group consisting of methacrylate, acrylate, C1 to C8 alkyl acrylate, and combinations of two or more thereof; and the ethylene acrylate dipolymer is substantially free of a third comonomer; and the acid copolymer comprises repeat units derived from ethylene and an acid monomer selected from the group consisting of (meth)acrylic acid, maleic acid, fumaric acid, maleic anhydride, fumaric anhydride, maleic acid monoester, fumaric acid monoester, and combinations of two or more thereof. |
