(3) 請(qǐng)參照本產(chǎn)品的數(shù)據(jù)表（MSDS）。

用途:

1.  氯乙烯的聚合：

LPO廣泛地應(yīng)用于水相懸浮聚合和本體聚合反應(yīng)中，聚合的溫度范圍為60-75℃，很多情況下，LPO和其它高活性的過(guò)氧化物復(fù)配使用，例如，過(guò)氧化二碳酸酯類(lèi)（過(guò)氧化二碳酸雙-4-叔丁基環(huán)已烷），或過(guò)氧酯類(lèi)（過(guò)氧化新癸酸-1，1，3，3-四甲基丁酯），可以增加其反應(yīng)活性。

2.  乙烯的聚合：

LPO使用于高壓聚乙烯的聚合引發(fā)，由于它的溶解性較差，在很多情況下被過(guò)氧化異壬酰所取代，但是LPO的優(yōu)點(diǎn)是它可在常溫下保存。

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應(yīng)，聚合反應(yīng)溫度為60-90℃。

4. ABS樹(shù)脂的聚合引發(fā)劑：

LPO同時(shí)也是ABS聚合反應(yīng)的重要引發(fā)劑，它和1，1-二叔丁基過(guò)氧化-3，3，5-三甲基環(huán)已烷(LQ-CH335)復(fù)配使用，具有很好的引發(fā)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.
