Abstract

The invention discloses continuous production equipment for a polymerization degree controllable reaction. The continuous production equipment comprises a photocatalytic reaction kettle and a composite stirring reaction kettle, a glass light-transmitting plate is arranged on the upper portion of the side wall of the photocatalytic reaction kettle, a baffle is arranged on the outer side of the glass light-transmitting plate, a cage type stirrer is arranged in the photocatalytic reaction kettle, a planetary tooth-shaped disperser is arranged on the upper portion of the inner wall of the composite stirring reaction kettle, and a frame type stirrer is arranged in the center. Reactants and a photocatalyst can be fully mixed by the cage type stirrer of the photocatalytic reaction kettle, and theamount of inlet light is adjusted by the baffle, so that the photocatalyst stably generates a catalytic effect, the non-uniform polymerization degree is avoided, and the molecular weights of most macromolecules are in a narrow range. After primary polymerization in the photocatalytic reaction kettle, the mixture is transferred into a composite stirring reaction kettle for more sufficient stirring, so that narrow molecular weight distribution can still be kept after the molecular weight is further increased, and a polymerization product with a controllable polymerization degree is obtained.

Description

technical field [0001] The invention relates to chemical equipment, in particular to a continuous production equipment for reaction with a controllable degree of polymerization and a use method thereof. Background technique [0002] Polymerization is a reaction in which the molecular weight of a monomer increases rapidly under the action of a catalyst. Due to reasons such as fast reaction speed and uneven dispersion, it is impossible to obtain macromolecules with uniform molecular weight after the polymerization reaction. The polymer actually uses A mixture of macromolecules of different molecular weights. Molecular weight distribution is one of the important indicators to measure the uniformity of polymerization. The molecular weight distribution of the polymer is too wide, and the system contains too many low molecular weight or high molecular weight components, which will affect the performance of the polymer: low molecular weight macromolecules Too much content will aff...
