Segalman et al. studied the room temperature and high temperature phase
behavior of weakly segregated PI-b-PPV (alkoxyphenylenevinylene) RCBCP
system consisting of PPV rods and PI coils with varying f
coil (0.42–89) but
constant PPV rod length (M n PPV = 3545 g/mol) (Olsen and Segalman 2005,
2006). All the samples exhibited L phases at low temperatures. However, with an

observations of PPV-b-PI system in the (c) weakly segregated and (d) moderately segregated
samples. (Adapted from Jenekhe and Chen 1998; Olsen and Segalman, 2005, 2006)
