| titleOfInvention | End-capped poly(aryl ether sulfone) polymers, poly(aryl ether sulfone) block copolymers, and corresponding synthesis methods |
| abstract | Described herein are end-capped poly(aryl ether sulfone) ("PAES") polymers and corresponding synthesis methods. The end-capped PAES polymers are end-capped by functionalizing a PAES polymer with a halophthalic diialkyl ester end-capping agent. It was surprisingly discovered that the resulting dialkyl phthalate end-capped PAES polymers could be synthesized with significantly improved end-capping conversion rates, relative to end- capped PAES polymers directly functionalized with traditional phthalic anhydride end- capping agents. It was also surprisingly found that by heating the isopropyl phthalate end- capped PAES polymers, the polymers could be converted to the corresponding phthalic anhydride end-capped PAES polymers, yielding a more efficient synthetic route to phthalic anhydride end-capped PAES polymers. |
