| 摘要 |
The invention relates to a process for preparing adhesive nanodispersions. According to the invention, the process consists in chemically or mechanically-chemically grafting the elastomer, wherein the chemical grafting takes place by the emulsion polymerization and grafting of a mixture consisting of a polychloroprene elastomer and methyl methacrylate in the presence of a catalyst, while stirring at 1700...1800 rpm for 2...3 h, at a temperature of 40...50°C and a pressure of 5 mmHg, and the mechanical-chemical grafting process takes place by grafting chloroprene elastomer with methyl methacrylate in the presence of a catalyst, on the roll, for 35...40 min, followed by the dissolution in dichloromethane and dispersion of the grafted chloroprene elastomer in the presence of surfactants. |
