Hello, everyone. So, this is my first time doing Chemistry at school and today my teacher assigned each student a topic in Chemistry to research and give a short presentation on it on Monday. He assigned me the topic of, Substitution Polymers. So, tonight I thought I might do some research on it. I searched online but...haha...nothing came up. All I keep getting is Addition and Condensation Polymers. So I am confused and a little scared now...what am I to do on Monday, because he has never taught these topics before. Is there such a thing as Substitution Polymers? If there is, can someone explain this to me or give me a link to a site that can, so I can at least have something to show on Monday? I am not ask you to do my presentation for me, haha. I just need some information, please. Thank you in advance.
