    Abstract: Coextruded polymeric article comprising first segments each having first and second opposed major surfaces and a thickness, the first segments comprising first material; second segments comprising second material, wherein adjacent first segments are joined together via a second segment, wherein at least 10 percent by number of the second segments extend from the second major surface past the first major surface of each first adjacent segment and has a distal end, the second segments having first and second opposed major surfaces, wherein there is a gap between adjacent second segments; and adhesive on the first and second major surfaces of at least every other second segment except a portion of the major surface adjacent to the respective distal end is free of the adhesive, wherein the first segments, second segments, and adhesive each extend continuously for at least 5 mm. Uses for coextruded polymeric articles described herein include adhesive articles and household cleaning products (e.g., as mops, dusters, brushes, cleaning cloths, and lint rollers).
