View Patent ↗An epoxy resin containing side-chain-tethered caged POSS and a preparation method thereof as well as epoxy resin material containing POSS-epoxy and a preparation method thereof are disclosed. The epoxy resin containing side-chain-tethered caged POSS (POSS epoxy) is formed by tethering of POSS group to the side chain of the diglycidyl ether of bisphenol A (DGEBA) epoxy resin. The preparation method of the POSS epoxy includes a step of reacting epoxy resin with caged POSS to form epoxy resin containing side-chain-tethered caged POSS (POSS-epoxy). The preparation method of epoxy resin material containing POSS-epoxy includes a step of reacting DGEBA epoxy resin with POSS-epoxy to get epoxy resin material containing POSS-epoxy. The POSS-epoxy is distributed evenly in the epoxy resin material with POSS-epoxy.
