Science Buddies: "Ask an Expert"

Hi!

I've been reading up on polymers recently and looking particularly at polypropylene. There's a lot of information on how it's formed from propene and the different types of polypropylene (isotactic/atactic etc), but nothing on what's on the ends of one of these chains.

Does it finish with a hydrogen? I assume it doesn't just have an empty space for a bond, and that there can't be an intact double bond (or there would be no way for the monomer to join the chain). Please help!

Hi JuliusCaesium,

Is your question related to a science fair project? This forum is intended for students, parents, and teachers working on K-12 science projects. If you are looking for help with homework or general science discussions there are other sites that should be able to answer you question.
