  • Patent number: 7943722
    Abstract: Provided is a flame-retardant polyarylate resin and a composition thereof, and more particularly, a polyarylate resin prepared by co-polymerizing 4,4?-dihydroxyphenylacetylene (DHPA), phthaloyl chloride (PC) and bishydroxyphenol (BHP) and a composition of the polyarylate resin. The polyarylate resin has lower heat release capacity than a conventional resin or a resin containing a halogen-based flame-retardant, is environmentally friendly, does not produce toxic materials, and has more excellent flame-retardancy than a conventional halogen-based flame-retardant and a flame-retardant resin. In addition, the polyarylate resin has excellent processibility and compatibility due to high solubility in a commonly used industrial solvent and has excellent thermal stability due to a high molecular weight.

  • Publication number: 20110097419
    Abstract: A process of the present invention is directed toward conducting highly selective, high yield post-polymerization reactions on polypeptides to prepare functionalized polypeptides. In certain embodiments, the polypeptides can be prepared by ring opening polymerization of N-carboxyanhydrides. In certain embodiments, the post-polymerization reaction is a “click chemistry” reaction. In certain embodiment, the “click chemistry” reaction is a triazole-forming reaction involving an alkyne on the polypeptide and an azide.

  • Publication number: 20110086995
    Abstract: Solid polymerizable diacetylenic monomer compositions, including compositions co-crystallized from a diversity of solvent systems under diverse cooling conditions, can exhibit diffraction patterns associated with the color development reactivities of the compositions. High reactivity compositions are disclosed and high reactivity and low reactivity phases can be identified. A low angle powder X-ray diffraction peak can indicate the presence of one or more crystal phases in a composition. A fingerprint region can exhibit fingerprint patterns of diffraction peaks associated with different reactivities. Information about polymerization of the diacetylenic monomers is disclosed using 13C nuclear magnetic resonance (“NMR”) characterization. Diacetylenic monomer compositions useful in ambient condition indicators, for example time-temperature indicators are disclosed.
