Embodiment 1
[0056] see Figure 1-10 , a kind of continuous process SAN resin production method based on plug flow reactor, comprises the following steps:
[0057] S1, heat up, continuously add heat medium to the inside of the reactor body 1 through the heat medium inlet 103 fixedly installed on the outer end wall of the reactor body 1, and pass through the heat medium outlet 104 pairs fixedly installed on the outer end wall of the reactor body 1 The heat medium injected inside the reactor body 1 is withdrawn, and heat medium circulation heating is formed inside the reactor body 1 to improve the ambient temperature of a plurality of reaction tubes 2 inside the reactor body 1;
[0058] S2, feeding, through multiple main feeding pipes 101 provided on the reactor body 1, styrene and acrylonitrile are added into the polymerization reactor according to the ratio of 3:1, and the molecular weight modifier is added into the polymerization reactor according to the ratio of 1000ppm;
