Abstract
Described herein are methods for making poly(aryl ether sulfone) (“PAES”) polymers and polymer compositions including the PAES polymers. The method includes reacting a first monomer and a second monomer in a reaction mixture including a base. In some embodiments, the first monomer, second monomer and base can be selected such that halogen salts are not formed during the reacting. In some embodiments, the method can also be a solvent free process. The PAES polymer and polymer compositions can be desirable in many application settings including, but not limited to, electronic components.
