The invention provides a styrene water-soluble synergic polymerization inhibitor. The inhibitor is composed of a solvent and effective components A and B. The solvent is a high-boiling-point alcoholic solution with the dilution effect and high solubility. The effective component A is one of 4-hydroxy-2,2,6,6-tetramethylpiperidinooxy and 4-oxo-2,2,6,6-tetramethylpiperidinooxy compounds; the effective component B is a succinimide compound. The mass content of the solvent is 60-65%, the mass content of the effective components is 35-40%, and the mass ratio of the component A to the component B in the effective components is (4-6):1. The styrene water-soluble synergic polymerization inhibitor is good in inhibition effect, small in kinematic viscosity, low in toxicity and convenient to store and convey, and has the good solubility in the styrene distillation process, the rectification yield of styrene can be effectively increased, and the inhibitor is better suitable for the industrial production requirement.
