LIGHT GENERATING MICROCAPSULES FOR SELF-HEALING POLYMER APPLICATIONS
A self-healing polymeric material includes a polymeric matrix material, a plurality of monomer mixture microcapsules dispersed in the polymeric matrix material, and a plurality of light generating microcapsules dispersed in the polymeric matrix material. Each monomer mixture microcapsule encapsulates a mixture of materials that includes monomers and a photoinitiator. Each light generating microcapsule encapsulates multiple reactants that undergo a chemiluminescent reaction. The chemiluminescent reaction generates a photon having a wavelength within a particular emission range that is consistent with an absorption range of the photoinitiator.

CYCLIC OLIGO(ARYLENE ETHER)S, PROCESSES FOR THEIR PREPARATION AND THEIR USE
The invention relates to a process for the manufacture of a cyclic oligo(arylene ether) which can be a cyclic oligo(dichloromethylene arylene ether) or a cyclic oligo(arylene ether ketone); the process comprises the step of causing an aromatic compound to react with a hexachloroxylene compound in a pseudo-high dilution environment. The invention relates also to new cyclic oligo(arylene ether)s and their use for the manufacture of acyclic poly (arylene ether)s, such as PEKK, by ring-opening polymerization.
