Do Inorganic Macromolecules Exist?

[lainthewired14]

Homework Statement

Hii!! I would like to know if all macromolecules are considered organic, since I've been trying to search for the inorganic ones but nothing came up. A few examples were given such as rubber, polypropylene and polyethylene, which are synthetic and do contain carbon. It has led me to believe the term "inorganic" is not being used as it is, and it's actually referring to the synthetic macromolecules. I would be really grateful if someone could explain this to me. Thank you and sorry for my English!!

Inorganic is a definition. That means there can be loopholes (the red part) in accepted usage:

An inorganic compound is most usually chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound. Some simple compounds that contain carbon and no hydrogen bonds are often considered inorganic.

Why? This is because a lot of chemistry foundations are old. Like 1800's and earlier. Some names and classifications are like that, arbitrary, so do not read too much into it.

So your answer is mostly no -inorganic macromolecules do not exist, or at least they are not called that.
Exception: graphite and diamond = inorganic macromolecules.
