Infrared and Raman spectroscopy of polypropylene
Erik Andreassen
- 01 Jan 1999
TL;DR: In this article, Fourier transform (FT) Raman instruments were used to analyze the scattered light in a modified FT-IR instrument, which excite in the near infrared (NIR) range (∼4000-11000 cm-1).

A novel passive micromixer: lamination in a planar channel system
TL;DR: In this paper, a passive micromixer is proposed to make a controlled 90° rotation of a flow cross-section followed by a split into several channels; the flow in each of these channels is rotated a further 90° before a recombination doubling the interfacial area between the two fluids.
Shear Testing of Polypropylene Materials Analysed by Digital Image Correlation and Numerical Simulations
TL;DR: In this article, the distribution of shear strains and strain states (triaxiality) were analyzed for two in-plane shear test fixtures (Iosipescu and V-notched rail), using digital image correlation and numerical simulations.

Haze of polyethylene films—effects of material parameters and clarifying agents
TL;DR: In this paper, the authors define haze as the fraction of (nor-mal incident) transmitted light that deviates from the directly transmitted beam by more than 2.5 (1).

Effects of processing parameters and molecular weight distribution on the tensile properties of polypropylene fibers
TL;DR: In this paper, the tensile properties of polypropylene fibers, produced in a short-spin line, are correlated with the parameters of the three processing stages (spinning, drawing, and annealing), and with the molecular weight distribution.
