    摘要： Three-dimensional polymeric article (100) having first (101) and second (102) opposed major surfaces, a first dimension perpendicular to a second dimension, a thickness orthogonal to the first and second dimensions, and a plurality of alternating first (107) and second (109) polymeric regions along the first or second dimensions, wherein the first (107) and second (108) regions extend at least partially across the second dimension, wherein the first regions (107) are in a common plane (115) and wherein some of the second regions (108) project outwardly from the plane (115) in a first direction (generally perpendicular from the plane), and some of the second regions (108) project outwardly from the plane (115) in a second direction that is generally 180 degrees from the first direction, where the first regions (107) have a first crosslink density, wherein the second regions (108) have a second crosslink density, and wherein the second crosslink density of the second regions (108) are less than the first crosslink density of the first regions (107). Embodiments of the articles are useful for example, for providing a dual-sided, textured wrapping film such that greater grip is realized both on an item wrapped by the film and the wrapped item itself.

    摘要： Polymers, particularly those used in pressure-sensitive adhesives, are prepared from a mixture of structural isomers of a secondary alkyl (meth)acrylate monomer. The mixture is made by dehydrating a biobased C2-C22 alcohol with a first acid catalyst using a continuous process to form a mixture of olefins, and reacting (meth)acrylic acid with at least some of the mixture of olefins in the presence of a second acid catalyst. The adhesives are characterized by exhibiting an overall balance of adhesive and cohesive characteristics, and containing biobased material.
