Republic of China ## SYNOPSIS Poly(ether ether ketone ketone)-poly(ether sulfone) (PEEKK/PES) block copolymers were prepared from the corresponding oligomers via a nucleophilic aromatic substitution reaction, and the A?" of the PEEKK segment was fixed a t 12,000, while the M,,'s of the PES segmen
## Abstract **Summary:** The poly(amidoamine)s (PAAs) ISA 1 and ISA 23 display pH‐dependent conformational change and pH‐dependent membrane perturbation. These properties confer potential for use as endosomolytic polymers for intracytoplasmic delivery of toxins and genes. Both polymers are relative
## Abstract **Summary:** A novel poly(__p__‐phenylene vinylene) (PPV)/poly(__p__‐phenylene ethynylene) (PPE) block‐copolymer was synthesized by a cross‐coupling polycondensation with Pd(PPh~3~)~2~Cl~2~ and a phase‐transfer catalyst, and was confirmed by ^1^H NMR and IR spectroscopy and elemental an
