Comb-type siloxane belongs to graft polymers with high density in segments of main backbone, which have considerable attracted interest of researchers due to unique architecture. Hydrosilylation reactions are used for synthesis of graft polymers. The aim of presented work is obtaining of photopolymers based on polydimethylsiloxane (PDMS). For this purpose, we have conducted hydrosilylation reaction of polymethylhydrosiloxane (PMHS) with allyl acrylate and vinyltriethoxysilane in the presence of Karstedt's catalyst in toluene. Nanocomposites are fabricated based on PDMS and reduced graphene oxide with different content in the range of 0.5–0.8 wt.%. Materials’ structure and composition are characterized by FTIR, NMR, TGA, DMTA, Raman, and SEM analyses in order to determine the structure, morphology, filler dispersion, defects and other characteristics.

Keywords: comb-type siloxane, hydrosilylation, nanocomposite, 3D printer
