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

其中的是乙烯， 也称乙烯。

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乙烯官能团， 它被称乙烯基。

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

好吧，基于乙烯的聚物是通过称加聚的过程形成的。

That ethene is sometimes called ethylene.

乙烯有时被称乙烯。

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乙烯基体的加成反应， 包括聚四氟乙烯。

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， 与另一个乙烯分子结， 形成另一个自由基。
