The effects of surfactants on the miscibility of polymers

Abstract

The surface tension of molten LDPE can be determined with the help of the pendent drop method, depending on the temperature and on the surfactant added. The critical micelle concentration was reached on addition of 1% of the surfactant. A four‐component mixture consisting of HDPE, LDPE, PVC, and PS, whose composition corresponded to that of collected waste plastics, was used to study the effects of the addition of surfactants on the applicational properties.

Ductility and Flame Retardancy Enhancement of PVC by Nanostructured Fly Ash

“…Therefore it can increase the polymer chain mobility and improve its adhesion behavior [27]. In the case of PVC/MCA-FA composites (Fig.…”

Surface Tension in Polymer Blends of Isotactic Poly(propylene) and Atactic Polystyrene

“…[24,25] The pendant drop apparatus established for this purpose largely corresponds to that described by Berger et al [23] Video image processing in combination with selected planes according to Andreas [20] was used for the drop shape analysis. The apparatus consisted, essentially, of a light source, temperature chamber in which the pendant drop is formed, an optical system to capture the image of the drop, and a data acquisition system to compute the interfacial tension from the drop profile (Tropfen C, Imtronic, Germany).…”

Swelling of acrylamide gels made at various onset temperatures: an optical transmission study

“…Though the term microgel has long been used and is well established, it is not completely satisfactory because it is only appropriate for the swollen state, ie if crosslinked macromolecules are dissolved 29. 30 Moreover, micro refers to dimensions of more than 1 µm, whereas the dimensions of microgels are usually in the nanometre range 31. However, in colloquial language ‘micro’ is also used for something very small.…”
