There are three main methods for preparing chlorinated polyethylene: the solution method, suspension method, and solid-phase method. This article studies the process of preparing chlorinated polyethylene by the aqueous suspension method, introduces the production process of chlorinated polyethylene, first understands the reaction mechanism of the chlorination reaction, then explores the production process of chlorinated polyethylene by the suspension method, and finds the optimal process conditions through experiments.
The results showed that the optimal reaction temperature for the chlorination reaction of chlorinated polyethylene was 135°C, the optimal amount of initiator was 3%, and the optimal amount of chlorine gas added was 1.5%/min. This article explores the influencing factors of the optimal reaction conditions, laying a theoretical foundation for industrial production after the suspension method.
