Polymerization and surface active properties of water-soluble amphiphilic polysiloxane copolymers modified with quaternary ammonium salts and long-carbon chain groups

Two water-soluble amphiphilic polysiloxane copolymers modified with quaternary ammonium salts (QAS) and long-carbon chain groups are synthesized by copolymerization. FTIR, 1H NMR, and 13C NMR are used to characterize the structures of the amphiphilic polysiloxane copolymers. The results show that two water-soluble amphiphilic polysiloxanes have high surface activity in the aqueous solution and excellent wettability. They can form hydrophilic films on the surface of materials to improve the wettability of materials. The whiteness of the polyester fabrics treated with the amphiphilic polysiloxanes obviously reduces. The color yields (K/S) of the dyed fabrics treated with the amphiphilic polysiloxanes slightly increase. The amphiphilic polysiloxanes have shade darkening effect on dyed polyester microfiber fabric. However, the reflectance spectra curves of the fabrics treated without and with the amphiphilic polysiloxanes undergo no significant change.
