摘　　要：聚醚的起始剂影响其性能。丁酸聚醚与丁醇聚醚比较,浊点较低,润湿性能、消泡性能则优于后者,热分解的难度也是前者明显大于后者。但两者的粘温特性基本相同。嵌段聚醚中,由于环氧乙烷和环氧丙烷的排列方式与无规聚醚不同,使其在浊点、润湿、乳化力和粘度等方面都明显不同于无规聚醚。The properties of copolyethers are influenced by their starting agents. As compared with random polybutanol EO/PO ethers,the heat-resistance, permeability and defoaming ability of randon Polybutanoic ethers are better, and the cloud point is lower. Because they both have the similar chain structures their characteristics of viscosity-temperature are the same. Both block copolyether and random copolyether have different values in cloud point,permeability, heat-resistance, emulsification , viscosity number, etc.
