I have thesis research to make electrospun fibers of PLA/PCL/PMMA/Collagen. I got recommendations that I should use ethyl acetate as solvent for PMMA since I want to mix it together with PLA, PCL, and Collagen. The question is how much PMMA with mW 350.000 is needed to be dissolve in ethyl acetate and is there any special conditions for PMMA to be dissolved perfectly? Thank you.

10 to 15% should be a good starting concentration or the same you are using for the spinning in acetone. From there on it's optimization until you have your desired outcome.
