Abstract

Poly‐(glycidyloxypropyl) phenyl silsesquioxane (PGPSQ) was combined with an organo‐layered titanate filler. The phase structure of the obtained composite was evaluated by XRD and TEM observations. Moreover, a burning test was carried out according to the UL‐94 test method. The extinguishing time of the nanocomposites was classified V‐0 even for the 1 wt % layered titanate content. Based on the results, it was clarified that the frame retardancy of the PGPSQ/organo‐layered titanate system was superior to the poly‐(glycidyloxypropyl) silsesquioxane (PGSQ)/organo‐layered titanate system, which was reported in a previous paper. In addition, the layered titanate as a filler also improved the ductility of the PGPSQ. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007
