A hydrophobic latex polymer having a small particle size is disclosed. Polymerized via a reaction mixture including a hydrophobic monomer, a macromolecular organic compound having a hydrophobic cavity such as a cyclodextrin, a surfactant that is sterically hindered from complexing with the macromolecular compound, and an initiator, the resulting latex polymer has a small polymer size, lacks grit, and is producible without undesirable reactor deposits.

Provided are a tetrodotoxin conjugate, a method for preparing same, and use thereof. A carboxyl-containing macromolecular compound and tetrodotoxin are used as the starting materials, and after a catalyst and a solvent are added, the tetrodotoxin conjugate is obtained by means of a coupling reaction. The carboxyl-containing macromolecular compound is selected from carboxylated dextran, carboxylated β-cyclodextrin, alginic acid, and polyacrylic acid. The tetrodotoxin conjugate can be used in the preparation of a sodium channel blocker and a medicament for treating neuropathic pain caused by chemotherapy, and possesses an analgesic effect associated with tetrodotoxin (TTX). In addition, the therapeutic window is increased, thereby greatly improving the safety.
