Abstract: Disclosed is a formulation comprising a copolymer comprising one or more bifunctional high refractive index first monomers comprising a high refractive index aromatic core and further comprising one or more UV- or thermally-reactive groups (A) and one or more second monomers comprising a high refractive index core and further comprising one or more groups capable of reacting to increase the solubility of the copolymer in aqueous media (B), and one or more solvents. The formulation may optionally contain additional components. Further disclosed are methods for forming optical thin films from the formulation and optical devices containing the optical thin films.

Abstract: Poly(cyclic acetal)s, methods of making same, and uses of same. The poly(cyclic acetal)s may have a number average molecular weight (Mn) of 10 to 3000 kiloDaltons (kDa) and over 50% of the chain ends may exclude hydroxyl groups. The poly(cyclic acetal) may be a homopolymer or copolymer(s) of poly(1,3-dioxolane) (PDXL). The poly(cyclic acetal)s may have one or more or all of: a thermal stability (Td,5%) of 337° C. to 392° C.; a thermal stability of (Td.50%) of 377° C. to 462° C.; or an Arrhenius activation energy (Ea) of 85.0 kJ/mol with 2 mol % of strong acid (e.g., pKa less than or equal to 4). Methods of polymerizing poly(cyclic acetal)s may comprise reacting cyclic acetal monomers with either Lewis acid catalysts and haloalkyl ether initiators or organic cation salt catalyst(s) and proton traps. Methods of chemically recycling poly(cyclic acetal)s into cyclic acetals may react poly(cyclic acetal)s with strong acids.

Abstract: According to one embodiment of the invention, a method for managing security for an organization is provided. The method includes receiving a plurality of requests from a plurality of parties. Each request is a request for permission to implement a deviation from a security rule. Each request includes a statement describing a benefit associated with the deviation. The method also includes determining a risk associated with the deviation. The method also includes deciding whether to approve each request based on the determined risk and the statement. The method also includes storing the requests and a status of each request. The status indicates whether the request is approved. The stored requests includes at least one approved request. The method also includes deciding, after a predetermined time period, whether to continue an approval of the approved request.
