Embodiment 1
[0029]
[0030] Wherein, the structural formula of octaepoxy modified silsesquioxane is as follows:
[0031]
[0032] The preparation method of above-mentioned universal polymer compatibilizer comprises the following steps:
[0033] (1) In a tank reactor, dissolve octaepoxy modified silsesquioxane in tetrahydrofuran at a ratio of 1kg / 10L, and add 2g of N,N-diisopropyl to the tank reactor base ethylamine, and then under the condition that the stirring speed is 10r / min and the temperature of the tank reactor is 30°C, the single-ended hydroxyl polystyrene is divided into five equal batches and added to the tank reactor successively, and two adjacent batches The interval time between the addition of single-ended hydroxyl polystyrene is 15 minutes, and the stirring reaction is continued for 5 hours after the addition is completed;
[0034] (2) Evaporate the mixed solution in the tank reactor after the reaction in step (1) to dryness to obtain solid A, then wash the obtained ...
