“…The calorimetric trace displays not only the main peak of fusion, but also other signals which are found in the melt above T m . This is a general feature [18][19][20][21][22][23][24][25][26][27][28][29][30] found on several polyolefins, for amylose and PEO (Appendix). The IR spectra reveal important changes due to the treatment, such as band displacement and change of intensity or position of the base-line related to the sample.…”

The calorimetric and infrared (IR) spectroscopy measurements of polyethylene oxide (PEO) are used to evaluate the deformation and relaxation that films experience during a temperature cycle (30°C–90°C–30°C). After melting, the intensity of some bands decreases by 10 to 70%. During the temperature cycle, the C–O band in the 1100 cm−1 region and the C–C–O deformation bands at 650 and 500 cm−1 show some new features. A network of cooperative oxygen-hydrogen interactions between the PEO chains form in films with special history, namely, in thermally treated films, in thin films prepared from gel forming solutions, and in thick films after aging. The interchain interaction network is suggested from the IR absorption bands in the 1200 and 900 cm−1 region and also from small bands at 1144 and 956 cm−1. The network seems absent or reduced in thin films. IR spectroscopy appears a sensitive technique to study chain conformations in PEO films and in other materials where order, disorder, and the formation of intermolecular interactions coexist.

“…However, it was found that in PE films prepared in controlled conditions, absorbance could be directly related to the sample thickness. A reliable extinction coefficient, ε, was obtained through the analysis of films of different thickness but the same history [26,29,[35][36][37][38][39][40].…”

The production of linear low-density polyethylene (LLDPE) yarns for artificial turf is an advanced extrusion process, which relies heavily on the polymer's semicrystalline structure and inherent strengthening mechanisms to obtain the tailored mechanical properties so typical for turf yarns: a combination of strength and resilience. This review aims to bring together all relevant aspects in the structure-materials-processing interaction triangle which is so strongly in evidence in this application, by first summarizing the specific structural origins of the properties of the semicrystalline LLDPE and then discussing how structure evolves during the different steps of the production process, to eventually come to the final product properties of the yarn.
