The Pd(II)\u2010terminated PPI is first prepared via polymerizing monomer 1\u00a0catalyzed with phenyl alkyne\u2010Pd(II) complex and then utilized to initiate the controlled Suzuki cross\u2010coupling polymerization of monomer 2, yielding various PPI\u2010<jats:italic>b<\/jats:italic>\u2010PF copolymers possessing controlled molar mass and narrow dispersity.
