Communication: The miscibility in blends of semirigid liquid-crystalline polycarbonate (LPC) with poly(vinyl alcohol) (PVA), partially saponited poly(vinyl acetate) (PVAc75) and poly(vinyl acetate) (PVAc) was investigated by means of differential scanning calorimetry and scanning electron microscopy. These measurements suggested that LCPC forms partially miscible blends with PVA and PVAc75. Blends of PVAc are immiscible. The side-chain hydroxy groups play an important role in improving the miscibilities of the blends.
