Vinylhydridosilsesquioxne: Synthesis and characterization of a potential filler material for vinyl-containing polysiloxanes

This paper reports the synthesis and characterization of an organic silsesquioxane (SQ) containing Si vinyl and Si H groups named as vinylhydridosilsesquioxane (SQVH-12). Detailed investigation of the structure of this organosilsesquioxane revealed that SQVH-12 has a highly cross-linked (polycyclic) Si O network of silsesquioxane with Si vinyl and Si H functional groups. Thermogravimetric analysis of the pyrolysis behavior of SQVH-12 yielded a high percentage of ceramic residue (-92%) at 1200 degrees C under an argon atmosphere. The presence of functional groups in SQVH-12 and the high rate of ceramic residue highlights the potential usefulness of SQVH-12 as a filler for vinyl-containing polysiloxanes. Thus, further research of SQVH-12 can find applications in a wide variety of areas such as additive manufacturing, protective coatings, and advanced composites.
