Abstract: Articles are provided, having a multilayer structure including (a) a first layer formed from polyolefin and including undercut features formed on and extending from an integral backing; (b) a second layer including an adhesive having a Shore D hardness of greater than 59 when cured; and (c) a third layer including a substrate. The second layer is interlocked with the undercut features, the third layer is adhered to the adhesive, and the second layer is disposed between the first layer and the third layer. A method is also provided including (a) depositing a polyolefin resin into a mold cavity to form a first layer including undercut features; (b) demolding the first layer from the mold cavity at a rate of at least 150 millimeters per minute; (c) applying a curable adhesive to the undercut features to form a second layer attached to the first layer; and (d) attaching a third layer including a substrate to the second layer.

Abstract: Compositions containing tetrahydrofurfuryl and/or alkyl-substituted tetrahydrofurfuryl esters of citric acid are provided. These esters of citric acid can be formed from renewable materials and can be used, for example, as plasticizers for various polymeric materials. The tetrahydrofurfuryl and/or alkyl-substituted tetrahydrofurfuryl esters of citric acid typically have a low odor, have good compatibility with a variety of polymeric materials, and can be used at temperatures often encountered during hot melt processing of polymeric materials.
