摘要：

Three types of inorganic/organic copolymers have been prepared in a one-step sol-gel process, and their thermal stabilities have been studied. The one-step sol gel process was carried out in mixtures of three monomeric components: HEMA (hydroxyethyl methacrylate)-VTES (vinyl triethoxysilane)-TEOS (tetraethyl orthsilicate), HDDA (hexanediol diacrylate)-VTES-TEOS and GPTA (glycerol propoxy triacrylate)-VTES-TEOS. Copolymers with HEMA, which is able to form a linear organic polymer, were the least thermally stable materials. They lost the highest proportion of weight during heat treatment to 600 degrees C and exhibited the lowest decomposition temperatures. Copolymers with HDDA and GPTA, which are able to form crosslinked organic polymers, had higher decomposition temperatures, and their weight loss during heat treatment to 600 degrees C was small. The skeletal densities of all copolymers increased slightly during heat treatment.
