Abstract

The invention discloses a linear-hyperbranched phosphate salt surface active agent and a preparation method thereof. AB2 type monomers are synthesized, then avterminal hydroxyl hyperbranched polymer is synthesized, a long chain is introduced into the middle end of the terminal hydroxyl hyperbranched polymer, unmodified hydroxyl continues to be phosphorylated, and the linear-hyperbranched phosphate salt polymer is synthesized. The hydroxyl long chain is introduced, so that lipophilicity is improved, terminal lipophilicity is modified into a phosphate base, the prepared polymer has multi-terminal hydrophilic groups and hydrophobic groups and can be used as the surface active agent, the dispersity, flame retardance, antibacterial property, antistatic property and other special properties can be given, and excellent surface activity and biocompatibility are achieved.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, in particular to a linear-hyperbranched phosphate salt surfactant and a preparation method thereof. Background technique [0002] Linear-hyperbranched polymer refers to a linear long-chain group or a linear block long chain at one end, and a hyperbranched polymer at the other end, which has several hydrophilic and lipophilic groups, making linear-hyperbranched surfactants With versatility and better surface activity. Meanwhile, hyperbranched polymers have a highly branched three-dimensional structure, which exhibit properties quite different from linear molecules, such as low viscosity, no chain entanglement, and good compatibility. In addition, hyperbranched macromolecules contain multiple end group molecules, and corresponding properties can be obtained through end group modification. [0003] Phosphate ester salt surfactants have good emulsifying, dispersing, wetting, solubilizing,...
