I am making polymer composite by solvent mixing method.
When I am trying to add filler solution in polymer solution it quickly get solidified. How to make them then uinform? It doesn't give time to ultrasonication also.
What is the maximum solubility limit of poly(4-methyl-1-pentene) in N,N, dimethylformamide? I gone through solubility parameter concept but I did not get the answer for maximum amount of polymer...
