Influence of morphological and conformational changes on the molecular mobility in poly(ethylene naphthalene-2,6-dicarboxylate)
(2004) In Macromolecular Symposia 212. p.479-484- Abstract
- Dynamic electric (DEA) and mechanical (DMA) analyses were combined to explore the relaxational processes in amorphous and semicrystalline poly(ethylene naphthalene-2,6-dicarboxylate) (PEN) samples. Differential scanning calorimetry measurements were carried out to investigate the crystallinity of the samples following isothermal annealing treatment at 443 K. The two secondary relaxations beta and beta*, the main alpha relaxation, as well as the rho-relaxational process, were revealed by both electric and mechanical viscoelastic responses of the PEN samples. DMA results clearly identified the above T-alpha loss factor peak, rho, as a probe of the cold crystallization. However, the association of both DMA and DEA investigations pointed out... (More)
