Abstract
The invention provides a suspension polymerization system and a suspension polymerization method using the suspension polymerization system. The suspension polymerization system is particularly suitable for a method for suspension polymerization of styrene-divinylbenzene. The suspension polymerization system comprises a compressor, a material preparing kettle, a tubular reactor A, a tubular reactor B, a solid-liquid separating device, a collecting kettle, an aqueous phase injecting device, a circulating pump and a plurality of pipe valves. The suspension polymerization system is adopted for suspension polymerization, for example, the suspension polymerization system is used for suspension polymerization of styrene and divinylbenzene; a prepared product is higher in yield; in addition, an aqueous phase generated in the polymerization reaction process is also recycled. Therefore by means of the technical scheme provided by the invention, the production cost of the suspension polymerization can be reduced; meanwhile, the production efficiency is improved, thereby having excellent application prospect and market potential.
Description
technical field [0001] The invention relates to the field of chemical engineering, in particular to a suspension polymerization system and a suspension polymerization method using the suspension polymerization system. The suspension polymerization system is especially suitable for the suspension polymerization method of styrene-divinylbenzene. Background technique [0002] The polymerization reaction in which the monomer is suspended in the dispersion medium in the form of small droplets is called suspension polymerization. Suspension polymerization is the polymerization of monomers suspended in water as small droplets. An initiator is dissolved in the monomer, and a small droplet is equivalent to a small unit of bulk polymerization. From the monomer droplet to the polymer solid particle, the polymer-monomer sticky particle stage is passed in the middle. In order to prevent the particles from sticking to each other, a dispersant must be added to the system to form a protect...
