摘要： A composition includes an epoxy-based curable adhesive having at least one an epoxy resin modified acrylonitrile-butadiene copolymer and at least one thermoplastic elastomer. The at least one thermoplastic elastomer is present in the curable adhesive as a penetrating polymer network. Further, an expandable article is composed of the composition, a reinforcing element includes a support and an expandable article, a method for reinforces cavities of structural components, and the composition is used as a shape memory material.

摘要： A thermally expandable composition includes at least one polymer P cross-linkable by peroxide, and at least one acrylate, and at least one peroxide, azodicarbonamide and a zinc compound. The thermally expandable composition leads to low odor formation and low ammonia emission during and after the foaming process. The thermally expandable composition further shows excellent properties in terms of expansion stability.
