Equilibrium Melting Temperature of Poly(ferrocenyl dimethylsilane) in Homopolymers and Lamellar Diblock Copolymers with Polystyrene

The equilibrium melting temperature,Tm,0, of poly(ferrocenyl dimethylsilane) (PFDMS) is re‐investigated using two PFDMS homopolymers and a PS‐b‐PFDMS copolymer (PS: polystyrene). The melting temperatures of samples crystallized at different crystallization temperatures,Tc, were found to depend in a nonlinear fashion onTc. Consequently, the Hoffmann–Weeks approach fails in determiningTm,0. The more reliable Gibbs–Thomson approach results in aTm,0 = (215 ± 11) °C for the PFDMS homopolymers, and aTm,0 = (179 ± 5) °C for the PFDMS microphases in the lamellar PS‐b‐PFDMS diblock copolymer. magnified image
