A bridged polysilsesquioxane-based flame retardant filler imparts flame retardancy to manufactured articles such as connectors and other articles of manufacture that employ thermosetting plastics or thermoplastics. In an exemplary synthetic method, a bridged polysilsesquioxane-based flame retardant filler is prepared by sol-gel polymerization of a monomer having two or more trialkoxysilyl groups attached to an organic bridging group that contains a fire retardant group (e.g., a halogen atom, a phosphinate, a phosphonate, a phosphate ester, and combinations thereof). Bridged polysilsesquioxane particles formed by sol-gel polymerization of (((2,5-dibromo-1,4-phenylene)bis(oxy))bis(ethane-2,1-diyl))bis(trimethoxysilane), for example, and follow-on sol-gel processing may serve both as a filler for rheology control (viscosity, flow, etc.) and a flame retardant.

Methods and formulations for modified silicone resins of Formula (II) are presented. Formula (II) comprises at least one of each of the following subunits: ##STR00001##
The R.sup.1, R.sup.2, R.sup.3, R.sup.6, R.sup.7, R.sup.8, R.sup.9, R.sup.10, R.sup.11, R.sup.12 and R.sup.13 are each independently selected from a group consisting of H, alkyl, alkenyl, alkynyl, and aryl. The X is selected from a group consisting of arylene, transition metal, inorganic oxide, and silsesquioxane. The values oft ranges from 1 to 10, y ranges from 1 to 200 and z ranges from 1 to 1,000. The elastomeric materials prepared from modified silicone resins display robust mechanical properties following prolonged exposure to high temperatures (e.g., 316 C. or higher).

A photochromic hydroxyurethane compound of the present invention is characterized in that, on condition of having at least one photochromic moiety as the photochromic minimal unit in a molecule, it has a hydroxyurethane constitutional unit represented by Formula (1):
XOCONH(1)
