Beschreibung
Zusammenfassung:	The present invention relates to the technical field of polymer material preparation, and provides a synthesis method for a large-particle-size polybutadiene latex. In the present invention, butadiene and a chain transfer agent are added to a reaction solution in batches to perform a polymerization reaction, and the polybutadiene obtained in the previous reaction can be used as a seed of the next polymerization reaction, such that multi-step seed polymerization is achieved. The method provided in the present invention has simple operation and a short reaction time, and the obtained polybutadiene latex has a narrow particle size distribution. In addition, the particle size of the obtained polybutadiene latex can further be controlled by controlling the number of reactions in the present invention, and under the condition that the total dosage of butadiene and the chain transfer agent is the same, the greater the number of reactions, the larger the particle size of the obtained polybutadiene latex. In addition,
