摘要

(US9512274) A flame retardant filler includes a bridged polysilsesquioxane prepared by sol-gel polymerization.  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.

主权利要求

(US9512274) 1. A flame retardant filler, comprising: a bridged polysilsesquioxane prepared by sol-gel polymerization of a monomer comprising two or more trialkoxysilyl groups attached to an organic bridging group, wherein the organic bridging group has a backbone portion that includes at least two oxygen atoms, and wherein the organic bridging group is halogenated. 4. A flame retardant filler, comprising: a bridged polysilsesquioxane prepared by sol-gel polymerization of a monomer comprising two or more trialkoxysilyl groups attached to an organic bridging group, wherein the organic bridging group has a backbone portion that includes at least one phosphorous atom. 6. A flame retardant filler, comprising: a bridged polysilsesquioxane prepared by sol-gel polymerization of a monomer comprising two or more trialkoxysilyl groups attached to an organic bridging group, wherein the bridging group contains a fire retardant group selected from a halogen atom, a phosphinate, a phosphonate, a phosphate ester, and combinations thereof.
