: The type of solvent, the solution polymerization kinetics of MMA-BA-AA system, the stability of the polymer solution, the viscosity, the inherent viscosity of the polymer, the molecular weight and molecular weight distribution, the glass transition temperature Etc .. The experimental results show that solvent selection is very important in solution polymerization.In the good solvent system, the polymerization rate of the system is fast, the stability of the polymer solution is good, the viscosity is small, the overall performance of the polymer is better than that of the polymer Good; The optimum amount of solvent is 25% ~ 40%.
