Abstract: Core-sheath filaments are provided that comprise cores having diene-based rubbers that are crosslinked by multifunctional acrylates, resulting in superior high-temperature performance adhesives. The adhesive compositions have excellent durability against oxygen and moisture, low and stable dielectric properties, and superior high-temperature performance. Methods of making core-sheath filaments having cores including diene-based rubbers that are crosslinked by multifunctional acrylates and uses for such core-sheath filaments.

Abstract: A pressure sensitive adhesive composition is described comprising a first block copolymer comprising polyvinyl aromatic end block and poly(vinyl aromatic/butadiene) copolymer block; at least 20 wt. % of a second polystyrene-polyisoprene-poly styrene block copolymer; and solid tackifying resin. The total amount of block copolymer typically ranges from 40-65 wt. % and plasticizing oil and liquid tackifying resin are present in a total amount of less than 20 wt.-% based on the total weight of organic components of the pressure sensitive adhesive composition. Also describe are adhesive articles and methods.

Abstract: The present disclosure generally relates to adhesive compositions, adhesive articles including the adhesive compositions, methods of making the adhesive compositions and articles, and methods of using the adhesive compositions and articles. The adhesive compositions of the present disclosure include a thermoplastic phenolic resin made from the reaction of (1) alkyl phenol (e.g., butyl- or octyl- or -nonyl) and formaldehyde; or (2) alkyl phenol (e.g., butyl- or octyl-) and acetaldehyde; or (3) alkyl phenol (e.g., butyl- or octyl-) and acetylene. The present disclosure also generally relates to adhesive articles including these adhesive compositions. The inventors of the present disclosure found that such adhesive articles exhibit excellent adhesion to architectural coatings with including low or no VOCs, deep base formulations, and/or formulations including primer in various conditions, including, for example, high humidity.
