Their thermotropic phase behavior was investigated by differential scanning calorimetry and POM. It was found that T(subscript S-N) w and T(subscript N-I), of PMMAZO was slightly increased with the increased of the mass ratio of liquid crystal block segments. PEO and PMMA block affected the liquid cystal behavior of PMMAZO. Meanwhile, PMMA and PMMAZO obviously influenced the crystals property of PEO segments3 which was decreased as the increase of molecular weight of PMMA and PMMAZO segments.
