文摘

PEMA-g-PPG graft copolymer was synthesized in BuOH at room temperature. One-pot, 100% conversion reaction between PEMA and AMPPG occurred. PEMA-g-PPG exhibited an amorphous, rubbery, bimodal structure. Separation properties were superior to those of PEMA, PDMS, and PEBAX. Overall process is inexpensive and accessible, with excellent scalability.
