文摘
- •
New diamine monomer containing 9-alkylated fluorene moiety was synthesized.
- •
Poly(ether imide)s (PEIs) were synthesized using new diamine monomer.
- •
PEIs showed good thermal stability, mechanical strength and low dielectric constant (蔚=2.35).
- •
PEIs showed good combination of gas permeability and permselectivity.
