In 2024, global Alpha-Methyl Styrene Dimer (AMSD) production reached approximately 5,374 Tons, with an average global market price of around US$ 5,675 per ton.,Alpha methylstyrene linear dimer is widely used in the synthesis and processing of polymers, petroleum modification, and the manufacture of pigments and fragrances. It can be applied to change the fluidity of plastics, significantly reducing the viscosity of polyolefin resins, making plastic material processing easier, and reducing energy consumption; As a plasticizer added to PVC, it can improve the processing performance of PVC melt, and the effect is better than DOP. It can be used as a partial substitute for DOP or as an auxiliary plasticizer; As a good processing additive in the manufacturing of polyolefin masterbatch, polyethylene (PE) blow molding, and polypropylene processing, it can increase the filling amount, improve rheological properties, reduce energy consumption, and enhance impact resistance. In addition, α - methylstyrene linear dimer and its saturated compounds can also be used as excellent fillers for soap, shampoo, and additives for various fragrances, and the product quality is stable after adding linear dimer to fragrances.

The α-MS cyclic dimer, as an organic compound of indenes, has significant applications in many fields. Due to its excellent compatibility properties, it can be used as a plasticizer to increase the plasticity of materials such as plastics. As a substitute for triphenyl phosphate added to triacetate fiber; In the production process of PVC hard transparent products, adding cyclic dimers can reduce melt viscosity, production energy consumption, improve product uniformity, increase internal lubrication, and significantly promote melting. It can be used as a material to replace DOP. In addition, cyclodimers can also be used as additives in the production of polyolefin fillers. By changing the amount of filler used, not only is the performance of the product not affected, but the cost is also reduced. Alpha MS cyclic dimer can also be used as a plastic processing aid added to polyvinyl chloride (PVC) and polyethylene (PE), which can reduce plasticizing time and equilibrium torque, thereby increasing thermal stability, improving fluidity and impact performance. In addition, it is also used as an intermediate in the synthesis of lubricating oils to improve the flame retardancy, impact resistance, and photothermal stability of materials. It serves as a medium for transporting inorganic particles in the electronics industry and can also be applied to optical systems. Due to its excellent properties, cyclodimers are also used as lubricants; And it can resist radiation, withstand a wide range of temperature changes, and can be used as lubricating oil in jet engines and rocket engines. Because it has the ability to resist atomic radiation, it can be used in specific nuclear power plants. Due to the fact that many expensive spices come from natural plants, they are relatively expensive. In order to reduce costs, people often add a certain amount of fillers, such as AMS cyclic dimers, to spices. Therefore, AMS cyclic dimers have great utilization value in industry and therefore have significant research significance.
