Volume change of PVC when dissolving VCM?
Thread Content
If we always consider PVC:VCM=1:0.3, how will the volume change? For example, if 1.4 kg of PVC with a volume of 1 dm^3 contains 30% VCM, what is its volume after that? (60 degrees Celsius) Thank you.
PVC does not dissolve VCM; rather, the spaces between the particles absorb VCM, and no swelling occurs. I’m not sure what the landlord is trying to ask.
PVC can swell VCM by about 30%, but I just don’t know the volume change after they swell. If adopted, reference can be made to the article \"Solubility of Vinyl Chloride in Polymers\" in the April 1989 issue of Acta Polymera Sinica. I just want to know a simpler formula, rather than the free volume model of Prigogine-Flory.
I’ve learned it! ! Isn’t the apparent specific gravity of PVC around 0.5? Also, calling it “solubility” seems odd.
VCM cannot dissolve PVC, so there is no such thing as solubility; however, VCM can cause PVC to swell
You are right. It should be said that VCM causes PVC to swell, but it is also understandable to say that VCM causes PVC to dissolve.
I think “solubility” is a term used in academia; it’s not necessary for a substance to be in liquid form for it to have solubility – solids can also dissolve gases.
