用途:

1.  氯乙烯的聚合：

LPO广泛地应用于水相悬浮聚合和本体聚合反应中，聚合的温度范围为60-75℃，很多情况下，LPO和其它高活性的过氧化物复配使用，例如，过氧化二碳酸酯类（过氧化二碳酸双-4-叔丁基环已烷），或过氧酯类（过氧化新癸酸-1，1，3，3-四甲基丁酯），可以增加其反应活性。

2.  乙烯的聚合：

LPO使用于高压聚乙烯的聚合引发，由于它的溶解性较差，在很多情况下被过氧化异壬酰所取代，但是LPO的优点是它可在常温下保存。

3. 丙烯酸酯和甲基丙烯酸酯的聚合：

LPO也可以用于丙烯酸酯的聚合反应，聚合反应温度为60-90℃。

4. ABS树脂的聚合引发剂：

LPO同时也是ABS聚合反应的重要引发剂，它和1，1-二叔丁基过氧化-3，3，5-三甲基环已烷(LQ-CH335)复配使用，具有很好的引发效果。

Purpose:

1.  Polymerization of vinyl chloride：

LPO is widely used in aqueous suspension polymerization and bulk polymerization reactions, with polymerization temperatures ranging from 60 to 75 ℃. In many cases, LPO can be used in combination with other highly active peroxides, such as peroxydicarbonate esters (peroxydicarbonate di-4-tert-butyl cyclohexane) or peroxyesters (peroxyneodecanoic acid-1,1,3,3-tetramethylbutyl ester), which can increase their reaction activity.

2. Ethylene polymerization：

LPO is used for polymerization initiation of high-pressure polyethylene, and due to its poor solubility, it is often replaced by isononyl peroxide. However, the biggest advantage of LPO is that it can be stored at room temperature.

3. Polymerization of acrylate and methacrylate：

LPO can also be used for the polymerization reaction of acrylic esters, with a polymerization temperature of 60-90 ℃

4. Polymerization initiator for ABS resin：

LPO is also an important initiator for ABS polymerization reaction. It is used in combination with 1,1-ditert-butylperoxy-3,3,5-trimethylcyclohexane (LQ-CH335) and has a good initiating effect.
