本文研究了乙酸乙烯酯在Al(C_2H_5)3和VOCl_3作用下的聚合条件,并且认为这个体采具有自由基聚合反应的特点。聚合的最佳条件是以环己烷为溶剂,于20℃反应10小时左右,AI(G_2H_5)3和VOCl_3的克分子比选用20:1.体采中微量氧气的存在是必要的,但氧气过量则有阻聚怍用。所得聚合物的性能与工业样品的性能基本相似,但随着聚合温度的降低,聚合物的规整度略有提高。
In this paper, the polymerization conditions of vinyl acetate under the action of Al (C 2 H 5) 3 and VOCl 3 are studied, and the characteristics of this body are characterized by free radical polymerization. The optimal conditions for the polymerization are as follows: the molar ratio of AI (G_2H_5) 3 to VOCl_3 is 20: 1 with cyclohexane as the solvent, and the reaction is carried out at 20 ℃ for about 10 hours. The presence of trace oxygen in the body is necessary. However, Excessive use of anti-agglomeration. The performance of the obtained polymer is similar to that of industrial samples, but with the decrease of the polymerization temperature, the regularity of the polymer is slightly increased.
