The first step in the degradation is most probably the classical ester scission reaction to give a carboxylic acid and olefinic end groups. Further ester scission on the adjacent ester groups of carboxylic acid and olefinic molecular chains can then lead to the formation of lower weight pyrolytic products, such as: CH〓=CHOCOPhCOOCH=CH〓、CH〓=CHOCOPhCOOH and HOOCPhCOOH, and they can pyrolyze continually to produce substrate pyrolytic compounds, such as: HOOCPhCOCH〓、PhCOOH、PhH、PhCOCH〓 and CO、CO〓. At the same time, a corsslinking cyclization reaction occurred of the formation of the gas products during the degradation of PET.

断裂大分子链端邻近羰基和乙烯基的酯键持续断裂，不断地形成小分子裂解产物，如：CH〓=CHOCOPhCOOCH=CH〓、CH〓=CHOCOPhCOOH以及HOOCPhCOOH，这些产物还会进一步裂解成分子量更低的小分子裂解产物，如：HOOCPhCOCH〓、PhCOOH、PhH、PhCOCH〓以及CO、CO〓等，与此同时，一部分乙烯基酯端基的大分子链碎片会发生支化而相互连接，再经&链脱离&和环化反应形成难燃的交联产物。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
