Abstract
A semicrystalline polyphenylsulfone, has the structure Formula (I) wherein n and R are defined herein. The semicrystalline polyphenylsulfone, which exhibits a crystalline melting point in a range of 215 to 270° C., can be prepared from amorphous polyphenylsulfone using a solvent-induced crystallization method. An additive manufacturing method utilizing particles of the semicrystalline polyphenylsulfone is described.
