Embodiment 1
[0020] Take 100 grams of AS1801, 0.5 grams of solid activator, 5 grams of accelerator, 0.1 gram of antioxidant, 1 gram of α, β-unsaturated acid, 0.01 gram of inhibitor and 0.1 gram of initiator tape In a four-necked flask with a stirrer, a thermometer, a condenser and an equal pressure funnel, place the four-necked flask in a programmed temperature-controlled oil bath. Get 5 grams of ethylenediamine and place it in an equal pressure funnel. With the agitator in a stirring state and the system under nitrogen protection, turn on the programmed temperature control device to heat the oil bath, and when the temperature of the system rises to 110°C, add ethylenediamine dropwise. During the dropwise addition of ethylenediamine, the temperature in the reaction system should be controlled below 150°C. After the ethylenediamine is added dropwise, keep it at about 150°C for 1 hour, then raise the temperature of the system to 190°C, and keep it for 6 hours. The temperature of the system...
Embodiment 2
[0022] Take 100 grams of AS1801, 2 grams of solid activators, 25 grams of accelerators, 0.5 grams of antioxidants, 1-10 grams of α, β-unsaturated acids, 0.05 grams of inhibitors and 0.5 grams of initiator A four-necked flask equipped with a stirrer, a thermometer, a condenser and an equal pressure funnel was placed in a programmed temperature-controlled oil bath. Get 25 grams of ethylenediamine and place it in an equal pressure funnel. With the agitator in a stirring state and the system under nitrogen protection, turn on the program temperature control device to heat the oil bath, and when the system temperature rises to 130°C, add ethylenediamine dropwise. During the dropwise addition of ethylenediamine, the temperature in the reaction system should be controlled below 150°C. After the ethylenediamine is added dropwise, keep it at about 150°C for 2 hours, then raise the system temperature to 200°C, keep it for 6 hours, then lower the system temperature to below 160°C and di...
