The present disclosure provides compositions and products formed therefrom. In particular, the disclosure provides polymer compositions and hydrogel-latex compositions in particular. Such compositions can include a water-soluble polymer, a natural or synthetic rubber latex, and a rheological stabilizer. The present disclosure further provides products and articles that include a coating layer of the polymer composition on at least a portion of a surface thereof. The coating formed of the polymer composition can impart improved properties to the product or article, such as improved moisture absorption, improved lubricity, and the like.

Provided are multilayer synthetic rubber compositions formed from a layer of a styrene block copolymer composition and a layer of one or more synthetic elastomers, such as polychloroprene, polyisoprene, nitrile rubber, styrene butadiene rubber, butyl rubber and polyurethane. The multilayer compositions find use in the manufacture of thin walled articles, for example gloves, particularly medical or industrial gloves.

In accordance with 37 C.F.R. § 1.121(b)(2)(i), please replace the abstract of the specification as filed with the following paragraph:

A method of making an electrically conductive and weatherproof enclosure includes mixing and melting an electrically conductive material, a latex rubber material, and a polycarbonate material to produce a weatherproof material mixture, blending carbon black with polyethylene to produce an electrically conductive additive, positioning an injection mold of the enclosure in fluid communication with an exit end of a heating barrel, injecting the weatherproof material mixture into an entry end of the heating barrel, introducing the electrically conductive additive through a lateral port of the heating barrel proximate to the exit end to partially mix with the weatherproof material mixture to produce an injection mixture, and injecting the injection mixture into the injection mold to produce the electrically conductive and weatherproof enclosure.
