The elastic material contains a crosslinked network formed from a branched block copolymer having a monoalkenyl aromatic midblock positioned between conjugated diene endblocks (e.g., butadiene-styrene-butadiene (“B-S-B”) triblock copolymer). Prior to crosslinking, the branched block copolymers have a relatively low viscosity and thus may be readily formed into a precursor elastic material (e.g., film, strands, web, etc.) that is subsequently crosslinked to achieve the desired elastic and mechanical properties. Crosslinking is typically achieved through the formation of free radicals (unpaired electrons) that link together to form a plurality of carbon-carbon covalent bonds at the conjugated diene endblocks.

  • Publication number: 20080242806
    Abstract: Water-soluble fluorescent particles are formed in a simple process. A mixture comprising a solvent, water, a fluorescent polymer dissolved in the solvent, and an amphiphilic molecule is provided. The fluorescent polymer comprises a hydrophobic segment. The amphiphilic molecule comprises hydrophilic and hydrophobic segments. The solvent is removed from the mixture to allow the fluorescent polymer and the amphiphilic molecule to entangle in the presence of water, thus forming the water-soluble fluorescent particles. In the formed particles, the hydrophilic segments of the amphiphilic molecule are entangled with one another, and the hydrophobic segments of the fluorescent polymer and amphiphilic molecule are entangled with one another. The amphiphilic molecule encapsulates the fluorescent polymer and at least some of the hydrophilic segments are exposed to render the particle soluble in water.
