I read some articles about how to synthesise solvent-free acrylic hot melt pressure-sensitive adhesive with UV-curable methods (photopolymerization), but all of them mention that to make a prepolymer or oligomer still use solvent and then evaporated before UV-irradiation process. Is it the only way or we can make prepolymer or oligomer without use solvent?

Hi Garuda,
Please refer this article. You can modify the composition as mention in this to adjust your needs.

You can try using emulsion polymerization in water medium. It would avoid using solvent, but you have to do experiments if incorporating uv curable additives possible. Good luck!
