FLAME-RETARDED TRANSPARENT POLYCARBONATE COMPOSITIONS
The invention provides a transparent polycarbonate composition comprising a polycarbonate resin and a mixture of flame retardants comprising (A) tris(2,4,6-tribromophenoxy)-s-triazine and (B) an aromatic sulphone sulphonate in the form of an alkali metal salt. The composition achieves a UL-94 flammability test rating of V-0 at a polycarbonate thickness equal to or less than 1.6 mm. Processes for preparing the composition are also disclosed.
BISPHENOL HYPERSORBENTS FOR ENHANCED DETECTION OF, OR PROTECTION FROM, HAZARDOUS CHEMICALS
The invention relates to strong hydrogen-bond acidic sorbents. The sorbents may be provided in a form that limits or eliminates intramolecular bonding of the hydrogen-bond acidic site between neighboring sorbent molecules, for example, by providing steric groups adjacent to the hydrogen-bond acidic site. The hydrogen bond site may be a phenolic structure based on a bisphenol architecture. The sorbents of the invention may be used in methods for trapping or detecting hazardous chemicals or explosives.
