Good question! The way we name polymers (what I make for my job) is to combine the names of the chemicals we used to make the polymers. I have seen a polymer called:
poly(methyl methacrylate-co-ethyl hexyl acrylate-co-styrene-co-methacrylic acid) which is probably one of the longest I’ve seen. What this means is this polymer is made from mixing and heating the chemicals; methyl methacrylate, ethyl hexyl acrylate, styrene and methacrylic acid.
