The preparation of synthetic resins is mainly realized through the polymerization reaction of monomers. Commonly used polymerization methods in the industry include propriety polymerization, suspension polymerization, emulsion polymerization, solution polymerization, slurry polymerization and gas phase polymerization.
1, the body polymerization: monomer in the initiator or the role of heat, light, radiation, without adding other media directly to the polymerization. The method of product purity, easy to operate, but the viscosity of the material increases with the reaction, mixing and heat transfer difficulties.
2, suspension polymerization: monomer in mechanical stirring or oscillation, dispersed into droplets suspended in water for polymerization. The method of low material viscosity, easy heat transfer and control, but the production capacity and product purity is not as good as the body polymerization method.
3, emulsion polymerization: monomer in the role of emulsifier, the formation of emulsion polymerization in water. This method has fast reaction speed and high molecular weight, but the emulsifier will affect the product performance.
4, solution polymerization: polymerization in the presence of solvent, the system is a uniform viscous solution. The method is easy to control, but the system is viscous, heat and mass transfer difficulties.
5, gas-phase polymerization: the gas-phase monomer and catalyst according to the specified amount of one-step synthesis into the reactor. This method has a short process and pure products, but requires a highly active catalyst.
