    • PURPOSE: A manufacturing method of hydrophobically modified alkylene oxide polyurethane is provided to give hydrophobically modified alkylene oxide polyurethane useful for solventless thickening agent of coating material by not existing materially or lack of volatile organic solvent due to no solvent. CONSTITUTION: A manufacturing method of hydrophobic reforming alkylene oxide polyurethane comprises a step of contacting polyisocyanate branching agent, water-solubility polyalkylene glycol, and solventless agent of the diisocyanate with polymerization catalyst under enough condition to form hydrophobically modified aklyene oxide urethane polymer. However, (1) the solventless agent is additionally included with hydrophobic capping agent before contacting with the catalyst, or (2) the hydrophobic capping agent is added to the agent after contacting with the catalyst. The molarity of glycol to polyisocyanate branching agent is 4-20, and the molarity of the total isocyanate to glycol hydroxyl group is 1.1-1.6.
    • 目的:提供疏水改性的环氧烷聚氨酯的制造方法,以提供疏水改性的烯化氧聚氨酯,其用于无溶剂的涂料增稠剂,由于不溶剂而不存在物质上或缺乏挥发性有机溶剂。 构成:疏水性重整烯化氧聚氨酯的制造方法包括使多异氰酸酯支化剂,水溶性聚亚烷基二醇和二异氰酸酯的无溶剂与聚合催化剂在足够的条件下接触以形成疏水改性的聚氧乙烯聚氨酯聚合物的步骤。 然而,(1)在与催化剂接触之前,除了疏水性封端剂之外还含有无溶剂剂,或(2)在与催化剂接触后将疏水封端剂加入到试剂中。 二元醇与多异氰酸酯支化剂的摩尔比为4-20,总异氰酸酯与二醇羟基的摩尔比为1.1-1.6。
