SBS (styrene butadiene styrene) ternary copolymer is a commonly used raw material for chemical production, widely used in plastic modification, road modification, waterproofing membrane and other fields. The following is the manufacturing method of SBS: 

1 Lotion polymerization 

lotion polymerization is one of the commonly used manufacturing methods of SBS. The method is to add styrene, butadiene monomer and emulsifier into water to form lotion, and then polymerize under the action of initiator to generate SBS lotion. This method has the advantages of low reaction temperature, simple operation, and stable product quality, but the production cost is high

2. Suspension polymerization method 

Suspension polymerization method is another commonly used SBS manufacturing method. This method involves adding styrene, butadiene monomers, initiators, and suspension agents to water to form a suspension system, and then conducting polymerization reactions under stirring and aeration conditions to generate SBS particles. This method has the advantages of low production cost, large product particle size, and high yield, but it requires strict control of reaction conditions to ensure product quality

3. Solution polymerization method 

Solution polymerization method is a less commonly used SBS manufacturing method. This method involves adding styrene, butadiene monomers, and solvents to a reactor for polymerization reaction under the action of an initiator to generate an SBS solution. This method is suitable for producing high molecular weight SBS products, but the production cost is high and requires a large amount of solvents

Regardless of the manufacturing method used, strict control of reaction conditions and raw material quality is required to ensure the quality and performance of the product. Meanwhile, due to the involvement of chemical reactions and high-temperature and high-pressure operations in the production process of SBS, it is necessary to strictly comply with relevant safety regulations and operating procedures to ensure the safety and stability of the production process

In summary, the manufacturing method of SBS needs to be selected based on specific production conditions and requirements to ensure that the quality and performance of the product meet relevant standards and application requirements.
