摘　　要：本文主要合成了一系列以醋酸乙烯酯和甲基丙烯酸十八酯为原料的双分子聚合体(DVA),并系统地改变了分子配比,同时从大连石油化工厂多次取样进行感受性评价,根据聚合物原料的不同配比对同种油样的不同感受性,并结合分析油样自身的特点,提出相关机理.A series of de-molecule polymer （DVA） with vinyl acetate and octadecyl acrylate were synthesized. The proportion of both materials by the numbers and at the same time put. The receptivity of the samplings from the Dalian petroleumchemical plant was evaluted. The results showed that the different polymer material ratio led the different receptivity. By Analyzing the oil appearance, a definite route and were the conceivabledepression mechanism put forward.
