heal.abstract The mechanisms of molecular mobility and of phase transitions in a thermotropic, comb-shaped, side-chain liquid crystalline polymer (LCP), poly-(ε-acryloyloxycaproyloxyphenyl)-n-butoxybenzoate (PABB) were studied by dielectric techniques (dielectric relaxation spectroscopy, DRS, and thermally stimulated depolarization currents, TSDC). Two subglass secondary relaxations, β and γ, were observed in TSDC measurements, at about -100 and -150°C, respectively. The β relaxation, as well as, the α relaxation, associated to the glass transition, were studied by DRS. en
