A monomer design strategy based on a bridged bicyclic thiolactone that produces stereo-disordered to perfectly stereo-ordered polythioesters is disclosed. The described polythioesters exhibit high crystallinity and full chemical recyclability. Such polymers possess intrinsic tacticity-independent crystallinity and chemical recyclability, tunable tacticities from stereo-disorder to perfect stereoregularity, as well as combined high-performance properties such as high thermal stability and crystallinity, and high mechanical strength, ductility and toughness.

Embodiments provide methods for assembling an apparel product. The methods include applying a composition to a portion of a major component of the apparel product or a portion of a minor component of the apparel product. The methods include applying the portion of the minor component with the portion of the major component via the composition. 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 with an adhesive. The methods include converting the composition to the adhesive to form the apparel product. The adhesive includes a material having a thioester bond.
