| Abstract: | A series of functional polyorganosiloxanes containing fluorocarbon side chain and amino groups had been synthesized by ring-opening polymerization. The raw materials used were Octamethyl cyclotetrasiloxane (D4), dodecafluoroheptyl-propyl-trimethoxylsilane (502) and γ-aminopropyltriethoxylsilane (550), respectively. FTIR, 1H-NMR, 13C-NMR, and 19F-NMR were used to characterize the copolymer structures. The surface properties of the functional polyorganosiloxanes emulsions were discussed. The results showed that the functional polyorganosiloxanes containing fluorocarbon and amino side chains had low surface tension and excellent water repellency. |
