- ItemCONDUCTIVITY CONTRIBUTION TO DIELECTRIC LOSS OF POLY(MONOCYCLOPENTYL ITACONATE)(HUTHIG & WEPF VERLAG, 1994) SANCHIS, MJ; CALLEIA, RD; GARGALLO, L; RADIC, D
- ItemTHERMAL EFFECTS ON THE STRUCTURE AND RELAXATION PROPERTIES OF POLY(MONOCYCLOPENTYL ITACONATE)(HUTHIG & WEPF VERLAG, 1995) CALLEJA, RD; SANCHIS, MJ; GARGALLO, L; RADIC, DThe effect of thermal treatment and subsequent chemical structural modifications on the viscoelastic and dielectric properties of PMCPI (poly(monocyclopentyl itaconate)) was studied. The low temperature relaxation (gamma-relaxation) is unaffected by the thermal history or chemical modifications. The intermediate relaxation (beta-relaxation) is shifted by about 40 degrees C to higher temperature after thermal treatment. The alpha-relaxation (related to the glass transition temperature T-g) suffers more striking changes when moving to higher temperatures.
