Cleanup: needs to be split[edit]
This item is for the entire class of polycarbonates, but a lot of the statements (e.g. cost, various numerical material properties) appear to be about a specific compound, presumably the most common type, poly(BPA carbonate). I created an item for the latter: poly(bisphenol A carbonate) (Q110254858), and these statements should be moved there. 73.223.72.104 18:53, 24 December 2021 (UTC)
- Most (if not all) items about topics like this one are messed up. Usually there is no distinction between macromolecule vs polymer (mixture of macromolecules) vs plastic vs classes/groups of macromolecules/polymers/plastics etc — everything is mixed into one item, just like in Wikipedia everything is described in one article. If you know how it should be done, just do it. I don't think there was any discussion about how polymers should be modelled in Wikidata (i.e. do we need distinct items about macromolecules, polymers and plasics, and how to model relations between such items).
