Orientational Measurements in Polymers Using Vibrational Spectroscopy
B. Jasse,J. L. Koenig +1 more
TL;DR: A review of the recent theoretical and experimental results which have occurred since the review of Zbinden [3] can be found in this paper. But the review is limited to infrared and Raman measurements since they are complementary to each other in their a...

Review Polarised Raman spectroscopy for the study of molecular orientation distributions in polymers
M. Tanaka,Robert J. Young +1 more
TL;DR: Polarized Raman spectroscopy is a vibrational spectroscopic technique that is used widely for the chemical and physical analyses of materials since it is both non-destructive and suitable for remote analysis as discussed by the authors.
Journal ArticleDOI
Characterization of biaxial orientation in poly(ethylene terephthalate) by means of refractive index measurements and Raman and infra-red spectroscopies
TL;DR: In this paper, the three principal refractive indices of poly(ethylene terephthalate) were found to be 1.645, 1.573, and 1.541.

Elucidation of the Chain Conformation in a Glassy Polyester, PET, by Two-Dimensional NMR
TL;DR: The chain conformation of glassy poly(ethylene terephthalate) (PET) was characterized by two-dimensional double-quantum nuclear magnetic resonance (NMR) and an average gauche torsion angle of 70 degrees was obtained.
Journal ArticleDOI
Enzymatic surface modification and functionalization of PET: A water contact angle, FTIR, and fluorescence spectroscopy study
TL;DR: In this paper, a lypolytic enzyme was applied to polyethylene terephthalate (PET) to investigate the changes induced by a lysergic enzyme on the surface properties.

Mechanical properties of solid polymers
TL;DR: A concise, self-contained introduction to solid polymers, the mechanics of their behavior and molecular and structural interpretations can be found in this article, which provides extended coverage of recent developments in rubber elasticity, relaxation transitions, non-linear viscoelastic behavior, anisotropic mechanical behavior, yield behavior of polymers and other fields.

Beziehungen zwischen elastischen Konstanten und Dehnungsdoppelbrechung hochelastischer Stoffe
Werner Kuhn,F. Grün +1 more
TL;DR: In this article, the optischen Doppelbrechung zur mechanischen Ruckstellkraft (dyn/cm2) erweist sich dabei als unabhangig von der Anzahl der pro cm3 der Substanz vorhandenen Kristallite.

Infrared spectra of high polymers
TL;DR: In this article, the spectral properties of polyethylene terephthalate and three deuterated analogs have been obtained in the region of 70 to 3600 cm-i, polarized spectra having been obtained down to 330 cm-l. This assignment suggests a modification of the proposed chain structure of this polymer.

Polarized Infrared Studies of Amorphous Orientation in Polyethylene and Some Ethylene Copolymers
B. E. Read,R. S. Stein +1 more
TL;DR: In this article, measurements were made of the dichroic ratios of a number of infrared bands for uniaxially deformed low-density polyethylene, and orientation functions were derived from the results on the conformationally sensitive amorphous bands at 1368/cm, 1352/ cm, 1303/cm and 1078/cm.
