Preparation and properties of high performance epoxy-silsesquioxane hybrid resins prepared using a maleimide-alkoxysilane compound as a modifier

摘要

An alkoxysilane compound possessing maleimide moiety (MSM) was prepared from N-(4-hydroxyphenyl)maleimide and 3-glycidoxypropyltrimethoxysilane and was used as a modifier of epoxy resins. In situ curing epoxy resins with MSM resulted in epoxy resins with good homogeneity. Just 5-10 wt % of MSM is sufficient to yield high glass transition temperature (165 degrees C), good thermal stability above 360 degrees C, and high flame retardancy (LOI = 30) to bisphenol-A-based epoxy resins.
