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

好吧，基于聚合物是通过称加聚过程形成。

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

其中最是， 也称。

That ethene is sometimes called ethylene.

有时被称。

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

同样事情也适用于官能团， 它被称基。

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

而且，种类繁多聚合物都是基于基体加成反应， 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自由基，它攻击附近另一个 pi 键， 与另一个分子结合， 形成另一个自由基。
