【摘要】 结合对体系所含双氧水浓度的测定，以乙酰氯法测量了合双氧水的丙烯酸酯－苯乙烯共聚物溶液体系的聚合物的羟值。证明了乙酰氯法较之酸酐－吡啶法有较高的测量精度。双氧水的存在对测量有很大的影响，要测量出聚合物的准确羟值，必须同时准确地测出体系的双氧水含量。更多还原

【Abstract】 The hydroxyl value analysis of acrylate-styrene copolymcr solution by usillg acetylchloride as an acetylating agent is discussed. The effects of the remaining polymerization initiator H2O2on the hydroxyl value analysis is also dealt with. It is illustrated that this method involving acstylchoride has higher accuracy than the method of using acetic anbydride.更多还原
