Autor: Rieky Steenbakkers, Cristian Hedesiu, Geert Vanden Poel, Ralf Kleppinger, Dan E. Demco, Victor M. Litvinov, Klaas Remerie, Bernhard Blümich

Publikováno v: Macromolecular Materials and Engineering. 293:847-857

Changes in phase composition and chain mobility in injection-molded isotactic poly(propylene), crystallized from the melt with slow cooling rate and subsequently quenched, associated with aging at temperature well above Tg for 150 and 1 000 h, are st

Study of Uniaxially Stretched Isotactic Poly(propylene) by 1 H Solid-State NMR and IR Spectroscopy

Autor: Dan E. Demco, Bernhard Blümich, Cristian Hedesiu, Klaas Remerie, Victor M. Litvinov

Publikováno v: Macromolecular Chemistry and Physics. 209:734-745

Changes in the amount of the rigid, semi-rigid and soft fractions, molecular mobility and domain thickness of uniaxially stretched iPP were investigated as a function of temperature, draw ratio, drawing temperature and drawing rate. Correlations are

Effect of Temperature and Annealing on the Phase Composition, Molecular Mobility, and the Thickness of Domains in Isotactic Polypropylene Studied by Proton Solid-State NMR, SAXS, and DSC

Autor: Ralf Kleppinger, Cristian Hedesiu, W. Gijsbers, Klaas Remerie, G. Vanden Poel, V. M. Litvinov, Bernhard Blümich, D. E. Demco

Publikováno v: Macromolecules. 40:3977-3989

A combination of DSC, SAXS, WAXD, 1H time-domain, and frequency domain NMR measurements was used for determining the amount of rigid/crystallinity, semirigid, and soft fractions of iPP. Changes in the rigid, semirigid, and soft fractions of isotactic

The effect of temperature and annealing on the phase composition, molecular mobility and the thickness of domains in high-density polyethylene

Autor: Cristian Hedesiu, Victor M. Litvinov, Ralph Kleppinger, Dan E. Demco, A. Buda, Klaas Remerie, Bernhard Blümich

Publikováno v: Polymer. 48:763-777

Molecular mobility, the thickness of domains and the amount of rigid, semi-rigid, and soft fractions of high-density polyethylene (HDPE) were characterized as a function of temperature and annealing time using time- and frequency-domains proton solid
