本文研究了不同交联度聚乙烯在有催化剂和无催化剂作用下的热重行为。交联倾向于略微促进聚乙烯的热分解，而在催化分解的情况下，交联倾向于降低催化剂对交联聚乙烯的活性，并且可以观察到，交联越多，催化裂化开始的温度越高。对这些差异进行了定性分析，表明与热热解相比，催化热解可以区分不同交联程度的样品。(c) 2005 Elsevier B.V.版权所有
In the present work, the thermogravimetric behaviour of polyethylenes with a different degree of crosslinking has been studied with and without catalyst. While crosslinking tends to slightly advance the thermal decomposition of polyethylene, in the case of catalytic decomposition, crosslinking tends to decrease the activity of the catalyst towards the crosslinked polyethylene, and it can be observed that the more crosslinked, the higher the temperature of the beginning of catalytic cracking. All these differences have been qualitatively analysed and have revealed that catalytic pyrolysis can differentiate samples with different degree of crosslinking in contrast to thermal pyrolysis.
