Language Fails Me (Because This Isn't Important)
Consider the humble car tires. (In some places tyres...) Yes, the vulcanization process takes many smaller molecules and gets them to be one big, (possibly) happy molecule. Note that most people will say the tire is vulcanized instead of monomolecular!
The problem with big molecules is that size just doesn't matter so much in most scientific and engineering applications. Because it doesn't matter so much, we do not really have (in English) nice words to differentiate them. This is why it's "vulcanized rubber" instead of "monomolecular rubber." The process and ensuing properties from it are more important than molecular size.
Additionally, plastics are also described in terms of cross-linking type and degree of polymerization. This affects properties in a much more dramatic way than individual molecule size. This is also why we talk about vulcanization: it's a method to achieve a very high degree of cross linking.
In the world of crystals, you just refer to the thing as a "[crystal name] crystal". Maybe you talk about a specific form or lattice structure of crystals, but those usually have names. (Ex: "a quartz crystal" or "Smithsonite".)
This convention also goes the same for glass, but with the added benefit of talking more about composition than structure. (Because glasses lack repeating structure by their very definition!)
In the world of metals, we talk about localized areas of homogeny as "crystals" or "grains", even though these crystals/grains may have actual metallic bonds crossing over to form one big crystalline structure. Like glasses, metals are talked about more in terms of composition (or "grades") and temper. Sometimes the process is more important because you are talking about a category, so individuals prefer that. For example, steel can be rolled, forged, or cast and you would refer to those categories as such.
TL:DR There Are No Words
There just isn't as much a demand for describing three different classes/uses of "monomolecular" with other words. We are more frequently more concerned with composition over size. You will need to have something made up to disambiguate these or just assume people will understand from context. (Because how often do you care if the tire has a sharp edge?)
