Synthesis and Characterization of Polymethylsiloxane with Pendant Fluorocarbon Side Chains

Abstract

For the purpose of combining the properties of polymethylsiloxane and fluorinated compound, hexafluorobutyl mathacrylate (HFBMA) was grafted to polymethylhydrosiloxane (PMHS) by hydrosilylation reaction in the presence of Karstedt’s catalyst. The prepared polymethylsiloxane with pendant fluorocarbon side chains (PMHS-g-HFBMA) was characterized by FTIR, 1H NMR and TGA. The results showed that the expected product was successfully formed. The surface property and solubility of the product were also investigated.
