A sorptive article is provided. The sorptive article includes a polyolefin, a wax which is miscible with the polyolefin at the melt temperature of the polyolefin but phase separates on cooling of the article, and sorptive particles distributed in the article. Also provided is a method for removing moisture or other vaporous or liquid material from air or an object in the environment utilizing a novel sorptive article of the invention.

[ What is claimed is:] [1.] A method for removing material from the air or from an object in the environment comprising preparing a sorptive article that comprises a polyolefin matrix, sorptive particles distributed in the polyolefin matrix, and a wax distributed within the polyolefin matrix, the wa

[ What is claimed is:] [1.] A method for removing material from the air or from an object in the environment comprising preparing a sorptive article that comprises a polyolefin matrix, sorptive particles distributed in the polyolefin matrix, and a wax distributed within the polyolefin matrix, the wax and polyolefin having been melt-blended and the wax having phase-separated from the polyolefin on cooling of the mixture, whereby the article is sorptive but sorption is retarded in comparison to an article in which there is a void in the article in the places occupied by the wax; protecting the article from premature sorption by laminating it to a removable film or incorporating it in packaging; and removing the film or opening the packaging to provide the sorptive article proximate said air or object from which material is to be removed.
