Well, ethene based polymers form through a process called addition polymerization.

好吧，基于的聚物是通过称为加聚的过程形成的。

And the simplest of those is ethene, also known as ethylene.

最简单的是， 也称为。

That ethene is sometimes called ethylene.

有时被称为。

Well the same thing goes for the ethene functional group, which is called a vinyl group.

同样的事情也适用于官能团， 它被称为基。

And, that a huge variety of polymers is based on the addition reaction of ethene based monomers, including Teflon.

而且，种类繁多的聚物都是基于基单体的加成反应， 包括聚四氟。

The molecule itself is now a newly formed free radical, and it attack another nearby pi bond, joining with another molecule of ethene, forming another radical.

该分子本身现在是一个新形成的自由基，它攻击附近的另一个 pi 键， 与另一个分子结， 形成另一个自由基。
