Study on the Surface Activity of the Copolymer Surfactant PVA-MA-PEGA

  • Publish Date: 25 Feb 1999
  • The critical micelle concentration (CMC), surface tension and interfacial tension of a copolymer are investigated. The copolymer is synthesized by the copolymerization of polyvinyl alcohol (PVA), methyl acrylate (MA) and polyethylene glycol acrylates (PEGA) in aqueous solution and has a certain surface activity. The interactions between the polymer and the OP series low-molecular surfactant are also discussed. It is found that with the increase of the content of the hydrophobic monomers, the hydrophobicity of the polymer molecules increases and the value of CMC decreases. When the copolymer surfactants are compounded with low-molecular non- ionic surfactant OP10, the system achieves the minimum surface tension 30.6 mN/m, and the minimum interfacial tension 0.36 mN/m respectively.
