摘要: The present invention provides a preparation method for high impact polystyrene (HIPS) and a HIPS prepared thereby. In the present invention, a chain transfer agent and/or a low-molecular-weight vinyl aromatic polymer is added to a mixture solution of a vinyl aromatic monomer, a solvent, a rubber and an adjuvant, and prepolymerization is performed under stirring, followed by final polymerization and devolatilization to form HIPS. In the present invention, the morphological structure of a rubber phase can be maintained by appropriately reducing a viscosity of a prepolymerized continuous phase. Within a certain range of shearing rate, the morphological structure of the prepared HIPS can be maintained to improve the impact strength.
