A water-based hydrogel polymer coating and a method of application to natural rubber or other elastomeric latex products are provided. The water-based hydrogel polymer is mixed with a blend of at least one elastomeric material to provide a hydrogel polymer blend composition. The water-based hydrogel polymer blend composition is applied in a single application to an elastomeric article, such as gloves, without additional solvents in the polymer blend composition and without a separate acid or chemical priming step. The water-based hydrogel coating herein provides increased lubricity to facilitate improved wet and dry donning of the elastomeric article.

An immersion-molded body, wherein: the immersion-molded body is obtained using a latex; the latex comprises a chloroprene-based block copolymer; the chloroprene-based block copolymer contains 5 to 30% by mass of a polymer block (A) and 70 to 95% by mass of a chloroprene-based polymer block (B); the polymer block (A) is derived from a monomer; when the monomer is polymerized alone, a polymer with a glass transition temperature of 80° C. or higher can be obtained; the chloroprene-based polymer block (B) includes a chloroprene monomer unit; and when the immersion-molded body is heat-treated at 130° C. for 30 minutes, a tensile strength at break of the heat-treated immersion-molded body measured in accordance with JIS K6251 is 17 MPa or more.

According to an exemplary embodiment of the present invention, provided is a latex composition for dip molding, which includes a copolymer latex formed by polymerizing an isoprene monomer, an ethylenically unsaturated nitrile monomer, and an ethylenically unsaturated acid monomer, wherein a dip-molded article made of the latex composition for dip molding exhibits a durability test result of 45 minutes or more.

An endoprosthesis has an expanded state and a contracted state, the endoprosthesis includes a stent having an inner surface defining a lumen, having an outer surface, and defining a plurality of apertures through the outer surface, wherein the apertures are arranged in a micropattern; and a coating (e.g., polymeric coating) attached to the outer surface of the stent. The coating includes a base and a tissue engagement portion including a second surface facing outwardly from the stent, the tissue engagement portion including a structure that defines a plurality of holes extending inwardly from the second surface toward the base. The holes are arranged in a micropattern. When the endoprosthesis is expanded to the expanded state in a lumen defined by a vessel wall, the structure applies a force that may reduce stent migration by creating an interlock between the vessel wall and the endoprosthesis.

Elastomeric articles, such as gloves, made from more than one layer, are provided. The gloves can include a first (grip side) layer in which a first colorant is compounded or integrated and a second (donning side) layer in which a second colorant is compounded or integrated. Alternatively, the gloves can include a translucent first layer and a second layer in which a colorant is compounded or integrated. Either arrangement can enable a breach of the first layer to be more easily detected, either due to the high level of contrast between the first layer and the second when a first colorant and a second colorant are utilized, or due to the translucence of the first layer as compared to the donning side layer, where the intensity of the second layer is increased upon a breach of the translucent first layer.
