PCL you can spin in various solvents. The most straightforward way to get bead free fibers is to increase the PCL concentration to have more chain entanglements.

Zahid Hussain

HFIP is best

Fabricio Nicolás Molinari

If you are using a PCL with MW 80000 you can get bead free fibers using CLF:DMF 80:20 an a concentration about 12%wt.

Also around 18%wt. In DMF will led you to bead free fibers.

I hope this can help you

Best regards
