Abstract
In a process of emulsion-polymerization in a polymerization system containing an acrylate or a methacrylate monomer at least 60%; the improvement which comprises carrying out the emulsion polymerization in a polymerization vessel having a film of a quinone-amine compound of not less than 3000 in average molecular weight on the inner vessel wall, said quinone-amine compound being prepared by addition-reacting an aromatic quinone and an aromatic diamine in a solvent medium having a solubility parameter of 9.0 to 12.2. According to the process, the polymer scale deposition can be prevented in the acrylate or methacrylate polymerization system.
