Abstract

Act. Polymerica 32 (1981) Heft 9 552 VICINI, CANETTI, SEVES and SADOCCO: Poly(ethy1cne terephthalate) : A comparison between inverse gas-chromatography and rate of solubilization in phenol Poly(ethy1ene terephthalate): A comparison between inverse gas-chromatography and rate of solubilization in phenol L. VICINI, M. CANETTI, A. SEVES and P. SADOCCO Stazione Sperimcntale per la Cellulosa, Carta e Fibre Tessili Vegetali ed Artificiali, 20133 Milano/ItaliaTlie morphology of semicrystalline polymeric materials (PETP) was studied by an etching technique and by isothermal inverse gas-chromatography. Using these two techniques the same results for semicrystalline isotropic materials were obtained and these results were found to depend only on the crystalline fraction. Isothermal inverse gas-chromatography permits an evaluation of the macromolecular orientation while the etching technique shows the same behaviour both for isotropic and anisotropic materials. Polyethylenterephthalat: Ein Vergleich zwischen umgekehrter Gaschromatographie und L6segeschwindigkeit in PhenolDie Morphologie von partiell-kristallinem PETP wurde mittels einer Btztechnik und durch umgekehrte Gas-Chromatographie bei konstanter Temperatur untersucht. Durch Anwendung dieser zwei Techniken wurden gleiche Ergebnisse fur teilkristalline, isotrope Proben gefunden, die nur von dem kristallinen Teil abhangen. Die umgekehrte Gas-Chromatographie bei konstanter Temperatur erlaubt eine Abschatzung der Oricntierung der Makromolekule, wahrend die Btztechnik fur isotrope und anisotrope Proben das gleiche Verhalten zeigt.

Electroweak corrections to charged-current e+e−→4 fermion processes: Technical details and further results

“…Finally, the effects of the complete O(α) corrections to various differential cross sections of physical interest are discussed and compared to predictions based on the double-pole approximation, revealing that the latter approximation is not sufficient to fully exploit the potential of a future linear collider in an analysis of W-boson pairs at high energies.August 2011 1 Some of the problems appearing in a first attempt of such a calculation were already described in Ref. [ 25]. 2 The recently proposed approach [ 35] to describe unstable particles within an effective field theory is equivalent to a pole expansion.…”
