Problems solved by technology

The viscosity conference brings a series of problems: the higher the viscosity of the polymerization system, the smaller the heat transfer coefficient, it is not easy to dissipate heat, and the reaction temperature cannot be controlled
The polymerization system is unevenly mixed, and it is easy to produce gel
The viscosity of the synthetic emulsion is too high, which is not conducive to the later application
