Embodiments provide methods of disassembling apparel products. The methods include exposing an adhesive of the apparel product to a composition. The adhesive is disposed at least partially disposed between a major component and a minor component of the apparel product. The adhesive includes a material having an imine bond or an iminium bond. The major component forms a base portion of the apparel product and is configured to be supported and worn at least partially over a portion of a wearer. The minor component forms a secondary portion configured to be coupled to the major component via the adhesive. The methods include separating the major component from the minor component adjoined by the adhesive.

Methods of making bearings using pressure sensitive macromolecular adhesive polymers and pressure sensitive polymer compositions capable of integrating fluoropolymeric properties with a catechol-amine functionality to form an adhesive system that allows bonding between metallic substrates and fluoropolymers are disclosed. Also disclosed are core-shell polymeric particles comprised of a core and a shell comprising a thermoplastic polydopamine polymer that may be prepared as a colloidal suspension and used as a hot-melt pressure sensitive adhesive capable of binding low surface energy materials, such as polyolefins and fluoropolymers, to diverse materials including metals in making bearings and/or bearing components.
