A variety of plates for footwear are provided including a polyolefin resin. Sole structures and articles of footwear formed therefrom are also provided. Methods of making the polyolefin resin compositions, plates, sole structures, and articles of footwear are also provided. In some aspects, the polyolefin resin composition includes an effective amount of a polymeric resin modifier. The effective amount can be an amount effective to allow the resin composition to pass a flex test, and in particular to pass a flex test without significant change in abrasion loss. In some aspects, the resin composition also includes a clarifying agent to improve optical clarity of the plate. In some aspects, the plates include a textile disposed on one or both of a first side and the second side of the plate. The textile can provide for improved bonding of the plate to other components such as a chassis or an upper.

Disclosed are a gradient resin, a preparation method therefor and the use thereof.

Polymer compositions are described that contain at least two different immiscible phases for producing molded articles having a swirl-like or marble-like appearance. The first phase, for instance, may contain one or more polyoxymethylene polymers. The second phase, on the other hand, contains one or more polymers that together have a melting point that is from about 5° to about 30° different than the melting point of the polyoxymethylene polymer. In one embodiment, the second phase may contain a thermoplastic elastomer, a glycol-modified polyethylene terephthalate, or a polyimide and may have a melting point that is higher than the melting point of the polyoxymethylene polymer. The second phase is present in the polymer composition in relatively low amounts, such as in amounts less than about 5% by weight. The second phase can contain a high concentration of colorants that creates a contrast of colors when the molded article is produced.
