Description

technical field [0001] The invention relates to the technical field of preparation of vinyl chloride and butyl acrylate suspension copolymer resin, in particular to a preparation method of vinyl chloride and butyl acrylate suspension copolymer resin. Background technique [0002] Polyvinyl chloride (PVC) is widely used in various fields of people's life because of its excellent comprehensive mechanical properties, flame retardancy, chemical resistance and low price. General-purpose resins have disadvantages such as high brittleness, poor impact resistance, and low strength. Severely restricts the development of polyvinyl chloride resin in specific fields such as impact modification and flexible soft products. Copolymerization of vinyl chloride and acrylate monomers can introduce long-chain alkyl acrylates into the PVC molecular chain, which can not only endow the copolymer resin Good internal plasticizing performance, and at the same time, it can also make the vinyl chloride...
