I want to dissolve a photo-polymerized resin that contains BisGma/TEGDMA/CQ/DMAEMA for a SEC analysis. I have tried different solvents like THF, Toluene, Acetone, dichloromethane.. but unfortunately none of these could dissolve it. So I am asking what solvent is used to dissolve this type of resin.
Indeed, it was the first solvent I've tried, but it didn't dissolve it.
Dear Belhani Mohamed Afif,
if the overall formulation functionality exceeds 2, it will cure into a covalently cross-linked network. For instance, TEGDMA has the functionality of 4. Such networks don't dissolve. They could only swell or they could be chemically degraded (sometimes improperly referred to as dissolution). Instead of molecular weight, you should measure the cross-link density. Please see our paper for further reference:
